Is there a way to find out the theoretical stretch of an elastic band?

I'm in the middle of doing an experiment where I find the heat dissipation by hysteresis through the stretching of an elastic band. I have experimentally found out how much heat is dissipated, but I was wondering if there is a way to theoretically find out the dissipated heat, most likely by creating a graph of the theoretical lengths of loading and unloading. The elastic bands are stretched with great forces, so they have non-linear extensions thus Hooke's Law doesn't work. Are there any other possible solutions?

I thought I could possibly use Poisson's ratio for rubber to calculate it, but I'm not sure what formula I could use. This might even just be too complicated for my level right now.
