Simulation of additive friction stir deposition using material point method
The Material Point Method (MPM) is a meshless well adapted to the simulation of solids under large deformation.
Currently, we aim to develop the MPM to simulate Additive Friction Stir Deposition (AFSD). This 3D printing technology has the potential to be used for metal recycling. Yet, the current physical understanding of this process is limited and simulations are needed to describe it. However, full-scale models of the AFSD are currently limited by the high computational cost of the MPM. This project aims to employ the MPM to simulate AFSD and in addition improve the computational efficiency of the Material Point Method without degrading its accuracy to achieve near-real-time simulation capabilities. This method could then be used to learn what is the temperature, strain and stress path taken by a portion of metal being printed, and eventually to understand how to tune the process to enable scrap metal recycling.
