Hyperelastic materials – input the strain energy density function

  I am wondering if I can input a strain energy density for a hyperelastic material. I see that I can put in experimental data using a response function. But in this case, I want to use the strain energy density function that other researchers found, not stress-strain data. I know that I could define a USERMAT, but since its hyperelastic (no plastic deformation), I am wondering if there is a simple way to just enter the strain energy density function without needing to define a USERMAT.
