Hi guys, Im new to this forum.
For my masters thesis, Im using Abaqus to model the failure of polyurea (modeled as a viscoelastic material).
My question is how can I define a failure stress or strain for viscoelastic materials in Abaqus???
Do I have to write a umat subroutine, and if so, how do I go about this, as I have minimal experience with abaqus subroutines.
Thanks for your response.
