The increasing use of viscoelastic materials in cyclic loading applications has created a need for an understanding of the thermomechanical coupling phenomenon of which mechanical energy exerted, in deforming a material is converted into thermal energy. Three basic approaches to a mathematical analysis of this phenomenon are reviewed and discussed in as similar a mathematical notation as possible. The theories are shown to produce similar forms for the constitutive relations although the basic approaches are considerably different. An experiment was performed on a solid circular cylinder of a urethane rubber and the results presented. Author, modified-PL
