Hyperelastic model Umat

Submitted by Nedved on

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.
