VUMAT for incompressible material
VUMAT for incompressible material
(OP)
I am writing VUMAT code for incompressible, reinforced hyperelastic material.I have two question about VUMAT. please answer it. I will be very appreciative.
1. The constitutive model is incompressible, so can I write a VUMAT for it or I should add an compressible term to the constitutive model and consider It's coefficient as big order? 2. since the material is reinforced, should I introduce local coordinate in the model and considere it as main coordinate for code? Thanks a lot for your consideration
