Mahmud M.S. Dwaikat

I do not think there is a "ready" option for this in abaqus because the theory itself about this subject is not decisive (yet). You have to write up your own UMAT for this behavior. What exists in abaqus is elastic orthotropic behavior, not inelastic.

Usama Al-Saffar

thanks Natividad Garcia ... I will take a look at it.

@Mohamed O. Helmy, that's very helpful for "elastic" model. I suppose the material will behave in "inelastic" way.

Thank you for your input @Mahmud M. S. Dwaikat
