If we want to define a new material behavior in the Abaqus, we must write subroutines and attach them to the Abaqus model for conducting the simulation. There are several subroutines for defining new material behaviors. The most famous one is the UMAT subroutine that enables us to define every mechanical constitutive behavior.
Unfortunately, using UMAT subroutine, writing some mechanical constitutive behaviors can be too complex and time-consuming.
In contrast, the USDFLD subroutine is easier to be used. We cannot use this subroutine for defining every new mechanical behavior. Still, in some cases, it helps us define new mechanical behavior faster and easier than the use of UMAT subroutine.
This tutorial compares the USDFLD and UMAT subroutines and explains two examples of using the USDFLD subroutine for conducting advanced simulations according to their reference papers.
