Implementing a subroutine using UMAT for the Sand Hypoplastic model in Abaqus?

30 April 2023 0 4K Report

I am trying to implement a subroutine using UMAT for the Sand Hypoplastic model in Abaqus. I am beginner to Abaqus, and I do not have experience with UMAT. I got the code from soilsmodels.com and it is attached here. There are many files and I do not know which one should be used or modified. Can someone please help me with implementing this model in Abaqus correctly.
