Hi everybody.

Is there any one who has a simple example of nonlocal damage model type integral under Abaqus user subroutine UMAT or Fortran ?

Thank you.

Best regards 🙂

What are you trying to do?
Why do you need a non-local damage model?

I am trying to implement a nonlocal damage model on cement based material, thats why I need an example to understand the integration scheme and implementation of the nonlocal damage or strain variable.

I will be glad if someone can help me.

Have you already solved the problem? There is an amount of papers treating the integration schemes of those kind of models. Search for Non-local Modelling of Ductile Damage: Formulation and Numerical Issues. I think is better to code by yourself based on explicit information about the algorithms. Other approach is to use the AceGen and AceFEM packages to get and prototype of what do you want to do. regards
