The paper describes the application of modeling approaches used in Computational Welding Mechanics (CWM) applicable for simulating Additive Manufacturing (AM). It focuses on the approximation of the behavior in the process zone and the behavior of the solid material, particularly in the context of changing microstructure. Two examples are shown, one for the precipitation hardening Alloy 718 and one...
Thermally induced residual stresses and residual distortions in the additive manufactured (AM) parts are two of the major obstacles that are preventing AM technology from gaining wide adoption. In this work, a three-dimensional thermo-elastic-plastic model is proposed to predict the thermomechanical behavior in the laser engineered net shaping (LENS) process of Ti-6Al-4V using Finite Element Method...
