Abaqus XFEM

Submitted by ivanie on Fri, 07/12/2013 - 14:26

Hello!

I'm trying to simulate crack initiation and growth in Abaqus (by VCCT and traction separation laws in frame XFEM).

I have 2 problems:

Hyperelastic model Umat

Submitted by Nedved on Thu, 07/11/2013 - 14:57

Good mornig everybody ,

I wrote a Umat routine for the Yeoh hyperelastic model,

In order to compare the built in yeoh model and my Umat subroutine , I apply a uniaxial displacement on a single element and compare the stress strain rates

the problem is that I obtain different curves for the strees strain rates , and a different deformation I can't figure out why ,

My question is, do you have any documents or links describing the theory for the Yeoh model, and could you please have a look at my Umat code, attached here.
