About ABAQUS UMAT

Hi

I am working on probailistic modeling of damages in composite materials. I have my own developed mathematical model for calculating damage probability. Now I am trying to use this model in ABAQUS to see the effect of damages with a certain probability. Please kindly let me know if there is any reference code or tutorial for UMAT where I can apply the damages with different probabilities.

Thanks in Advance
