Simulation of hyperelastic materials using Ansys workbench ?

06 June 2018 0 8K Report

Hi, using stress strain data of uniaxial tensile test, I fitted the curve using Mooney- Rivilin 5 parameters method of hyperelastic materials. But when I run the program a warning message appears informing that the stiffness of the material is unknown. So I get no results. Why ? Do I have to implement modulus of elasticity and poisson ratio?
