Product Overview:
This tutorial demonstrates how to simulate a welding or additive manufacturing process in Abaqus with a focus on predicting residual stresses. The model uses a two-step thermal-mechanical approach, starting with a thermal analysis followed by a mechanical simulation linked via predefined fields. The video also introduces advanced modeling techniques such as element birth (material addition) through Python scripting and the use of UTEMP and DFLOW subroutines to customize temperature distribution and material activation. This efficient and simplified tutorial is ideal for engineers and researchers seeking to learn FEA simulation of WAAM or welding-induced stresses in under 15 minutes.
