We are glad to announce that our next PhDTalks Seminar will be held on Tuesday 16^th May in Room 2.1.3 (Building 2), from 5:15 pm to 6:30 pm CET. 

PhDTalks is a series of seminars and discussions between PhD students. The events are aimed at providing a place to network and get in contact with many of the projects developed in our department. 

Speaker Giacomo Rizzieri will talk about “Numerical simulation of 3D Concrete Printing: challenges and opportunities”. 

At the end of each event a small refreshment funded by the department will be available.

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.
