Giacomo Rizzieri, postdoctoral researcher at our Department, has been selected for theIDEA League Fellowship Exchange Program 2026/2027, promoted by Politecnico di Milano within the IDEA League alliance.
The programme supports research visiting periods at the partner institutions of the alliance — TU Delft, ETH Zürich, RWTH Aachen University and Chalmers University of Technology — with the aim of strengthening international collaborations and fostering joint research projects. Giacomo Rizzieri will spend three months atETH Zürich as a visiting researcher with the Computational Mechanics Group, led by Prof. Laura De Lorenzis.
Out of all the proposals submitted, the Selection Board chaired by the Vice-Rector for Talent Development awarded a grant to the ten highest-ranked applications, assessed on the quality and originality of the research proposal, the strength of the collaboration with the hosting institution and the potential for future competitive funding.
Il prossimo appuntamento con la serie di incontri PhDTalks si terrà Martedì 16 Maggio nell’aula 2.1.3 (Edificio 2), dalle 17:15 alle 18:30 CET.
PhDTalks 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 ongoing projects sviluppati nel nostro dipartimento.
Lo speaker Giacomo Rizzieri condurrà un seminario dal titolo “Numerical simulation of 3D Concrete Printing: challenges and opportunities”.
Al termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento.
Sarà possibile seguire la conferenza anche online al seguente link.
Abstract:
3D Concrete Printing (3DCP) is rapidly gaining momentum in the building industry, as it could be the way to achieve a fully automatized and more sustainable construction process. However, before a large-scale adoption of this technology takes place, it is necessary to address some issues both at the practical and numerical levels. The development of reliable computational tools would provide a better understanding of the printing process, while also enabling the prediction, in a design framework, of its outcomes. In this talk, it is presented a numerical model to simulate the extrusion and layer deposition phases of cementitious materials. The model assimilates fresh concrete to a homogeneous weakly-compressible fluid and solves the Navier-Stokes equations in a Lagrangian framework with the Particle Finite Element Method (PFEM). Different numerical challenges will be addressed regarding the imposition of time-dependent moving boundary conditions, the accurate treatment of inter-layer contact and the reduction of the computational cost.
Speaker’s bio:
Giacomo is a PhD Candidate in Structural, Seismic and Geotechnical Engineering (37° cycle) at Politecnico di Milano. He has a Master of Science in Structural Engineering obtained in 2021 at Politecnico di Milano. Currently, he is in the second year of his PhD and he is involved in the development of new computational tools to simulate 3D Concrete Printing. In his free time Giacomo enjoys hiking, reading and watercolor painting.
