Abstract
Laser-Directed Energy Deposition (L-DED) is a layer-by-layer additive manufacturing technique designed primarily for the manufacture of metal parts. A major problem with this additive manufacturing process is the presence of residual stresses and strains within the manufactured part. This project is part of a Cifre thesis between the MATIM Research Unit and Platinium 3D, whose experimental results will be used. This project proposes the thermomechanical properties of H13 tool steel in order to simulate the L-DED process for the design of beads, surfaces and cubes. Simulations are carried out on ABAQUS software. The focus is on the study of residual stresses and strains by varying various simulation parameters, such as substrate temperature, laser power or laser trajectory.
