FINITE ELEMENT CONSTITUTIVE MODELLING (MOHR-COULOMB)

Is it possible to find the Mohr-Coulomb constitutive model umat for Abaqus?

or generally a Mohr-Coulomb subroutine written in fortran?

Thank you!!!

You can find many fortran codes for constitutive models in the following book and its accompanying program HYPLAS.

COMPUTATIONAL METHODS FOR PLASTICITY, theory and application by

de Souza Neto, Peric and Owen

THANK YOU!! I WILL HAVE A LOOK AT THIS BOOK. I HOPE I 'LL FIND SOMETHING USEFULL.

THANK YOU ONCE AGAIN.

Hi everyone:

 
Now, I need to
establish a finite element model to simulate the process of using the single
diamond to grind the Continuous
Fiber-reinforced ceramic matrix composites. And , I want to study by ABAQUS.
But , I don't know how to identify the surface property when i use the cohesive
elements . And the other one is that I do not know  how to identify the parameter in the brittle
cracking model. What puzzled me most is that I don't know the relationship of
the parameters in brittle cracking , brittle failure and brittle shear.


I hope I can get help from you! Thank you!
