Reply To: Hyperelastic materials – input the strain energy density function

[Aurojyoti Prusty]

Hi Heidi,

Yes, you can define a hyperelastic material using only the strain energy density function. In engineering data, you drag and drop the Hyperelastic model of interest and then input the material parameter related to that strain energy function (If you know it already). If you do not know, then you need to curve fit the experimental data. For example, If I try to input a simple Neo hookean energy density function, I need to define Initial shear mod. and Incompressibility parameter D1. Same procedure for other strain energy density function.

 

Hope this Helps.

Thanks,
