Hi every one
I m working on modeling anisotropic hyperelastic model for human cornea
in Ansys v.10 ,and I derive the coefficients of constitutive three terms strain energy (volumetric,isotropic,anisotropic) from literature.
But I faced the problem in modeling this material in Ansys v.10
and I dont have information about how to use UMAT in modeling this material.
I need some help on predifined macro for anisotropic hyperelastic matrial model
Any help with this problem would be appreciated.
Thanks a lot.
