Abaqus AWI Plug-in Explained: Step-by-Step Workflow for Welding Simulation
Welding simulations are inherently complex, as they require accurate geometric representation, multiple weld passes, temperature-dependent nonlinear material behavior, and carefully defined thermal and structural boundary conditions. Capturing all of these details typically demands significant time and effort from the user. In this blog, we will provide an overview of the AWI plug-in user subroutine and its integration with the Abaqus Legacy framework for welding simulation . AWI Plugin The AWI plug-in is designed to leverage the capabilities already present in Abaqus Legacy for welding simulation. It employs a sequentially coupled procedure, beginning with a thermal analysis that computes the temperature field during welding Process. This analysis uses the Goldak heat-source model to approximate the heat flux generated by the welding torch. The computed temperatures are subsequently transferred to a structural model to evaluate the residual stresses and distortions produced by the w...
