Themo-Mechanical Simulation for Additive Manufacturing using GPU capacities
This work proposes to implement a thermo-mechanical simulation using GPU capabilities in order to drastically decrease the simulation time. This will aim at modeling the distortion occuring during the Laser Powder Bed Fusion process. The result will be benchmarked against both real printed part and commercial simualtion solutions (ANSYS).
Additive Manufacturing has shown outstanding capabilities to revolutionise the manufacturing indsutry. Nevertheless, these technologies still present significant bottlenecks due to the high number of influecing parameters. Due to the very high thermal gradient induced by the process, reisdual stresses are arising, potentially leading to part deformation. In the past decades, many simulation of the process have been sucesfully led. Yet, even if the results are representative of the reality, the computing time remains are a limiting factor of such simulations.
