Input strain energy density

      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 it is 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.
