SUMMARY:TIM approach: a thermodynamic standpoint for nonlinear soil-structure interaction
DESCRIPTION:Giovedì 8 Giugno si svolgerà presso l’aula 7.1.1 (Edificio 7 – Piazza Leonardo da Vinci\, 32) un seminario dal titolo “TIM approach: a thermodynamic standpoint for nonlinear soil-structure interaction” tenuto dal Dr. Davide Noè Gorini\, post-doc presso l’Università Sapienza di Roma. \nAbstract: \nThe frequency- and amplitude-dependant effects of soil-structure interaction under seismic conditions tend to be oversimplified in design and are commonly roughly modelled in large-scale assessment of structures\, with occurrence of unrealistic predictions of the ductility and displacement demands for the structural members. This seminar explores an analysis approach to account for salient features controlling the dynamic response of soil-structure systems\, overcoming limitations of existing practice-oriented methodologies and providing an essential description of reality. It consists of a class of Thermodynamic Inertial Macroelements (TIMs) simulating the macroscopic response of geotechnical systems in the nonlinear analysis of structures. TIMs reproduce a combined nonlinear and inertial response under multiaxial conditions of different foundation types\, including abutments\, shallow and deep foundations. The hardening response is derived within a consistent thermodynamic approach\, using hyper-plasticity\, and is bounded by the ultimate capacity of the geotechnical system. Inertial effects developing in a geotechnical system under dynamic loading are simulated through appropriate participating masses. TIMs are implemented as a new class of multiaxial materials in OpenSees. Applications of the proposed approach are discussed\, from the seismic analysis of peculiar soil-structure layouts to the large-scale assessment of infrastructural systems. \nSpeaker’s bio: \nDavide Noè Gorini is a post-doc at Sapienza University of Rome. He graduated in Civil Engineering in 2015 at Sapienza University of Rome\, where also obtained a PhD in Structural and Geotechnical Engineering in 2019\, working on a soil-abutment microelement representation for seismic assessment of bridges. He privileges open-source numerical environments for sharing knowledge without barriers\, such as OpenSees and open supercomputing resources. His current reseach fields concern: development of a thermodynamic inertial macroelement approach for soil-structure interaction; seismic performance of bridges\, buildings and tunnels; computational tools for soil-structure interaction applications in OpenSees; analysis and design of dissipative foundations and seismic-protection solutions; constitutive modelling for geomaterials and seismic assessment of natural slopes.

SUMMARY:Silicon based micromechanical actuators
DESCRIPTION:Lunedì 12 Giugno si svolgerà presso l’aula Beltrami (Edificio 5 – piazza Leonardo da Vinci 32) \, un seminario dal titolo “Silicon based micromechanical actuators” tenuto da Harald Schenk\, Professore presso il Fraunhofer Institute for Photonic Microsystems della Brandenburg Technical University (Germania). \nSarà anche possibile seguire il seminario online al seguente link. \nAbstract \nFraunhofer IPMS is a leading research and development institute in the field of micromechanical sensors\, & actuators\, and systems based on them. The most important fields of application are smart industrial solutions\, mobility\, and medical & health. The presentation starts with a brief introduction of the institute and then turns to the field of micromechanical actuators. Three different classes of electrostatic microactuators based on silicon are currently investigated and developed at IPMS. The first class are comb actuators\, which are used for driving of scanning mirrors for 1D and 2D light deflection. Typical application examples are LIDAR systems for autonomous vehicles. The second class are highly integrable actuators used for micromirror arrays with a million addressable single mirrors per chip. These arrays are deployed\, among other applications\, in microlithography as programmable mask. In a current research project\, they are also being further developed for use in holographic displays. The third class of electrostatic actuators presented in the talk are novel bending actuators that achieve high deflections at small electrical voltages. They form the basis for micropositioning systems with a displacement of several hundred micrometers but also of novel micro loudspeakers and ultrasonic transducers.

SUMMARY:Locally resonant vibro-acoustic metamaterials as NVH solutions – applications by KU Leuven
DESCRIPTION:Lunedì 12 Giugno si svolgerà presso l’aula Beltrami (Edificio 5 – piazza Leonardo da Vinci 32) \, un seminario dal titolo “Locally resonant vibro-acoustic metamaterials as NVH solutions – applications by KU Leuven” tenuto da Elke Deckers\, Assistant Professor presso la KU Leuven Faculty of Engineering Technology (Belgio). \nSarà anche possibile seguire il seminario online al seguente link. \nAbstract  \nLightweight materials and designs have been largely used in a variety of engineering applications due to the increasingly stringent ecological as well as economical requirements. However\, lightweight structures typically combine low mass with high stiffness\, which in turn leads to an impaired Noise\, Vibration and Harshness (NVH) insulation performance. Classical solutions to improve the vibro-acoustic performance of systems often involve the addition of mass or volume\, which conflicts with the current trends towards lightweight designs. Locally resonant metamaterials (LRMs) have recently emerged and shown potential in the field of noise control engineering\, allowing lightweight designs while achieving a superior noise and vibration insulation performance in tunable frequency ranges\, referred to as stop bands\, which are frequency zones where free wave propagation is inhibited.\nThis presentation explains the basic concepts of locally resonant vibro-acoustic materials and shows the potential of this type of solution for noise and vibration mitigation applied to industrial automotive and aerospace relevant problems\, where different production processes and materials are used. \nSpeaker’s biosketch \nElke Deckers received her MSc degree in Mechanical Engineering from KU Leuven in June 2008. During her PhD studies at the same university\, she developed an alternative prediction method for mid-frequency vibro-acoustic analysis including poro-elastic materials. She received her PhD in December 2012 with a thesis entitled “A wave based approach for steady-state Biot models of poroelastic materials”. Holding a postdoctoral research grant of the Research Foundation – Flanders (FWO)\, she extended her research field to the numerical and analytical modelling of complex lightweight material systems\, including viscous materials\, metamaterials and meta-porous systems\, and the development of supporting fast numerical prediction techniques. She did a research stay at Cambridge University and a short research stay at LAUM. She was appointed Assistant Professor at KU Leuven Campus Diepenbeek in 2019\, where she is currently broadening her domain of expertise to include also the production of lightweight material systems by polymer processing techniques like injection moulding and thermoforming. This way\, she aims to close and exploit the full (digital) loop ranging from design\, over manufacturing to the actual performance of the product.

SUMMARY:PhDTalks | Assessment and retrofitting of deep foundations of existing bridges
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 13 Giugno nell’aula 2.1.3 (Edificio 2)\, dalle 17:15 alle 18:30 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento. \nLo speaker Matteo Corigliano condurrà un seminario dal titolo “Assessment and retrofitting of deep foundations of existing bridges”.  \nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSarà possibile seguire la conferenza anche online al seguente link. \nAbstract: \nMost of the infrastructures in Europe are approaching their design life and\, therefore\, their safety has to be reassessed according to the more severe design standards.  Nowadays the foundations of existing bridges are verified using models based on simplified assumptions\, which make the retrofitting measures often unsustainable. \nThe ultimate goal of the research is the introduction of a tool\, allowing a rapid and reliable evaluation of the foundation performance and providing hints for the most rational retrofitting. To this aim\, the results of finite element numerical analyses on a real case study have been theoretically interpreted\, obtaining significant insight in the mechanical response of pile groups. The innovative tool under development will lead to a more aware and sustainable design of bridge foundations retrofitting measures. \nSpeaker’s bio: \nMatteo is PhD candidate in Structural Seismic and Geotechnical Engineering and has a Master degree in Civil Engineering – Geotechnics.\nHis mainreserach interest is the interaction between soil and critical infrastructures (bridges\, emnbankments and tunnels).\nHe is now focused on the assessment and retrofitting of deep foundations of existing bridges.\nHe spends his free time playing tennis\, skiing and honing his photography skills.

SUMMARY:PhDTalks | Effects of stimulated autogenous self-healing of Ultra High-Performance Concrete slabs under repeated impact loading
DESCRIPTION:Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Giovedì 22 Giugno nell’aula Fassò\, dalle 17:15 alle 18:30 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento. \nLo speaker Niranjan Prabhu Kannikachalam condurrà un seminario dal titolo “Effects of stimulated autogenous self-healing of Ultra High-Performance Concrete slabs under repeated impact loading”.  \nSarà possibile seguire la conferenza anche online al seguente link. \nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nAbstract:  \nThis paper reports on an experimental investigation on the self-healing capabilities of Ultra-High-Performance Concrete (UHPC) subjected to a drop-weight test. The impactor weight was 10 kg\, dropped from the height of 1 m on the center of the specimen with dimensions 29 x 29 x 4 cm3 (± 1 cm)\, with fixed corners and a continuous bottom support near the edges. Two types of self-healing were studied: stimulated autogenous self-healing with crystalline admixtures and autonomous self-healing with macro-capsules containing polyurethane. To pre-crack the specimens\, a repeated impact was performed on the same specimen. The different healing conditions for autogenous self-healing were submersion\, wet/dry cycling in water\, or in saline solution (12 hours wet/12 hours dry)\, and exposure to an environment with 95±5% RH. The self-healing evaluation was made using natural frequency analysis\, microscopic crack closure monitoring\, and laser measurements of the ductility. The test moments were at impact testing\, and after 1 month\, 2 months\, and 4 months. The rebound height of the impactor and the crack formation during a drop weight test were analyzed using a high-speed camera and Digital Image Correlation. At the end of the healing period\, all the specimens were tested to failure and the improvement of impact resistance due to self-healing was evaluated. Based on the natural frequency analysis and surface crack closure\, the healing efficiency for autogenous self-healing increased for samples stored at 95±5% RH\, in wet/dry cycling\, and submerged. In comparison\, autonomous self-healing specimens were tested to failure on the same day\, an hour after pre-cracking. \nSpeaker’s bio: \nNiranjan Prabhu\, an enthusiastic and committed Ph.D. student\, is dedicated to exploring the characterization of self-healing concrete performance in extreme loading scenarios. He is currently enrolled in the joint doctoral program at Politecnico di Milano (36th cycle) and Ghent University\, where he is also a valued researcher in the Self-healing concrete group of the Smartincs network. Niranjan’s primary objective is to contribute significantly to the field through his research endeavors. In addition to his research pursuits\, Niranjan actively participates in scholarly discussions\, attends conferences\, and collaborates closely with fellow researchers\, fostering a dynamic academic community.

SUMMARY:Tough Architected Concrete Enabled by Robotic Manufacturing and Bio-inspired Schemes
DESCRIPTION:Venerdì 30 Giugno si svolgerà presso l’aula Beltrami (Edificio 5 – piazza Leonardo da Vinci 32) \, un seminario dal titolo “Tough Architected Concrete Enabled by Robotic Manufacturing and Bio-inspired Schemes” tenuto da Reza Moini\, Assistant Professor of Civil and Environmental Engineering presso l’università di Princeton (New Jersey\, USA). \nAbstract \nIn the face of climate changes\, the world’s growing population\, and decaying infrastructure\, there is a need to develop stronger\, tougher\, and more resilient civil infrastructure materials. Nature offers abundant relevant insight for developing resilient engineering materials. Two primary challenges are engineering the mechanics of strong and tough design motifs found in biological materials and implementing their fabrication via advancing manufacturing processes such as additive manufacturing techniques.  This seminar presents a bio-inspired approach for the purposeful design of architected cement-based materials. Construction materials typically suffer from a brittle response and low fracture toughness compared to other ceramic counterparts. Here\, we propose engineering several toughening mechanisms informed by nature\, into the conventionally brittle construction materials (such as concrete) with a quasi-brittle and ductile response and significantly enhanced toughness property. These designs are enabled by a variety of manufacturing techniques\, including additive processes. Layer-by-layer additive manufacturing commonly leads to processing-induced weak interfaces. By harnessing the weak characteristics of the interfaces and materials architecture\, we engineer the ability for damage delocalization in the material. This seminar makes the case that additive manufacturing offers the opportunity to harness the role of heterogeneous interfaces\, in favor of materials’ mechanical properties. Development of non-conventional automated technologies such as robotic additive manufacturing processes across multiple scales will be presented as the necessary tools to achieve such resilient infrastructure materials. \nSpeaker’s biosketch \nReza Moini joined the Civil and Environmental Engineering Department at Princeton University as an assistant professor in January 2021. He is directing the Architected Materials and Additive Manufacturing (AM2) Lab at Princeton and is an associated faculty with the Institute of Materials as well as the Andlinger Center of Energy and Environment. Moini completed his Ph.D. in the Lyles School of Civil Engineering at Purdue University in 2020. \nHis current research focuses on understanding the mechanics of architected and functional civil engineering materials with toughening mechanisms inspired by natural material\, and developing new processing techniques that enable them. His work is motivated by the intellectual challenges in mechanics of intrinsically brittle materials and designing tough and flaw-tolerant materials without changing the materials’ composition. \n  \n
