take a look here, you can find the UMAT and VUMAT subroutine of the modified GTN damage model.

Goodluck
In Static and Dynamic/Implicit Steps, there is rotational body force load in Load modulus, but in Dynamic/Explicit Step there is not such a load. Is there any way to model this load in Dynamic/Explicit?
