I am simulating a metal cutting process in Abaqus / explicit and want to implement a damage model using the VUSDFLD and VUHARD subroutines. As it is the first time I am going to write a subroutine and I am not experienced with programming, I do not have idea on how to do it.
Does anyone could share any examples of these two subroutine models (pdfs or a fortran file) from which I can base my work on? It would be a great help!
Thanks
It's been a while since I worked on this, but I think the two files here should help you: I used a user-defined boundary condition to store the position of the tool tip so that elements are only deleted there; the deletion is done using VUHARD with a johnson-cook law.
I am giving ABAQUS Subroutine/UMAT Lectures here:
