I am simulating a soil problem with Mohr-Coulomb criterion, and find that elastic modulus is a function of equivalent plastic strain. My question is How to define a elastic-plastic material whose Yong' modulus is a function of equivalent plastic strain for in Abaqus for Mohr-Coulomb materials?
You could in principle have your modulus depend on a user-defined field variable, and then use a ser subroutin (USDFLD/UFIELD) and from that use GETVAR to get the current value of the plastic strain and set the field variable accordingly.
Using the relationship, figure out the stress strain in excel. Input both of them as stress to plastic strain.

You can use USDFLD subroutine and define young modulus as a function of PEEQ.
