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 progetti 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.
