I would like to use XFEM to simulate cracks based on the stress field calculated by the UMAT. Does anyone have an idea about this topic?
Hi Jianwei, i have done crack analysis using contour integral..if you want i can send you the cae file..
Hi i'am also facing similar difficulty in XFEM,What is UMAT?
Pls give your mail id
the general enrichment functions used in X-FEM provides a basis that included crack opening displacements for Linear Elastic Fracture Mechanics (LEFM) problem. This means that we are in the elastic domain at any given time.
For a more general plastic case (not supported by Abaqus) It may be replaced by the one derived from the Hutchinson–Rice–Rosengren elastic–plastic asymptotic fields, but you'll have to write all the X-FEM code and the level set method to define the enriched elements.
Can I use XFEM in ABAQUS 6.13 with my own plasticity coupled damage initiation and evolution criteria developed in UMAT?.

Hi Jianwei,
According to your previous question, do you got the solution for that?. I have to try to link between UMAT (ductile damage model) with XFEM, but unfortunately, the result from solution dependent variables (SDV) are not really accurate.

Do you have any experiences before?.
Many thanks.
