Simulation of Additive Manufacturing of Metals
Simulation of Additive Manufacturing of Metals
Fast Finite Element (FE) framework with selective mesh coarsening to simulate additive manufacturing processes was developed. The new method allows unlimited flexibility to choose the level of mesh coarsening during the building process. The simulation shows stress formation along build direction (Z) during the printing process of a cylinder (200 layers) using Direct Metal Deposition (DMD) technique. Implemented in ABAQUS
