A UMAT Code In ABAQUS - Progressive Failure Analysis

H.Rahnama's picture

I have written a UMAT code in ABAQUS. This UMAT degrades the young modulus of an isotropic elastic material at a point when the VonMises stress at that point reaches a specific value. It can be seen as a simple progressive failure code. I have applied this UMAT code to a Notched plate under uniform tension.

The problem is that exactly before the damage initiation, the ABAQUS/Standard diverges. I am sure that there is a very simple mistake that I just can't see!
:)

You can download the Input file of the model and the UMAT code in the following link. I will be so thankful if anyone could help.
