Nastran Orthotropic Analysis Question

Nastran Orthotropic Analysis Question

Nastran Orthotropic Analysis Question

(OP)
Dear All,

I am running an orthotropic analysis using solid elements. The material vendor supplied all the elastic constants (ExEyEzGxGyGzNxNyNz). They also supplied (C11,C22,C33,C44,C55,C12,C13)which I believe is derived from classical equations. I have successfully ran both linear and non linear analysis with similar results using orthotropic material properties.


Is there any way to convert these constants to some type of Hyperelastic material constants (C10,C01) Mooney Rivlin and use non linear analysis? Would it make a difference since I am looking for stiffness anyway and the loads are fairly low.

Thanks,

THECADGUY
