Hello all,
I am learning to write an ABAQUS VUMAT subroutine for Deshpande Evans (DE)/ Preston-Tonks-Wallace Material (PTW)constitutive model. I didn't write a subroutine before. I would appreciate any guidance toward the development of a subroutine. If anyone can share a VUMAT subroutine for DE/PTW model it would be of great help!
Thank you!
Best Regards,
Arif
