How can I compute heat generated by the dissipation in rubber material?

Does anybody have some experience with the computation of heat, or temperature rise, in rubber material? I simulate the viscoelastic behavior of rubber by using Simos model (1987), where the viscous response is presented by the stress like internal variables. It would be nice if someone can suggest me some literatures or papers, where I can get the idea how to change this internal variables into the heat.

It is not too difficult to convert the dissipated energy to heat and temperature rise. All you need to do is to:

1) return the appropriate amount of dissipated energy from your user-material
2) Specify the specific heat, and thermal conductivity of the material
3) Instruct your FE software to use coupled thermal and heat transfer solution scheme

Abaqus, for example, can do this without problems.
