XFEM in Abaqus

Submitted by M Abdullah on

Hi

I am new to modelling and am trying to model a plate with a middle crack using Abaqus.

 What is the difference between modelling a cohesive and LEFM crack growth (I know cohesive involves plasticity and the traction/displacement curve and LEFM is for brittle materials).

 For cohesive, I used max principal stress for damage criteria and damage evolution based on energy criteria.

Hi Everyone:

We wanted to make sure everyone knew about this symposium, tucked away under the nanotechnology category, for the fall 2013 MRS meeting. Abstracts are due soon. We expect a heavy mechanics component for this symposium.
