This research investigates the application of the Inherent Strain method in Abaqus, an effective numerical strategy for simulating Laser Powder Bed Fusion (LPBF) in metal additive manufacturing. For this purpose, we have implemented the DFLUX and USDFLD subroutines using Fortran.
In this GitHub repository, we have shared the USDFLD subroutine developed for this project, completely, which determines whether the part's temperature has exceeded a critical threshold and activates the element if it has. But, you need also other subroutines, and python scripts, as provided in our website.
