Abstract:

This paper surveys the development and present status of stress analysis for problems in which thermo-viscoelasticity plays an essential role. For many polymers, the sensitivity of their viscoelastic characteristics to temperature variation, their poor heat conductivity and the dissipation of mechanical work into heat during viscoelastic deformation generate such problems. Needed physical characteristics and their formulation into constitutive relations are discussed. Categories of problems which call for different approaches are described and some representative examples are presented. Limitations of present formulations and methods of analysis are discussed.
