Does anyone know the form of the equation that ANSYS uses to curve-fit biaxial stress-strain data for a 2-parameter Mooney-Rivlin model?
The regression is said to be linear and the help document seems only to discuss the strain energy density function.
In the special equibiaxial circumstance, it seems the equation should derive and significantly simplify to a function of the two coefficients (C01 and C10) and the stretch ratio, lambda.
Thanks in advance.
