The Foundations of Thermoplasticity - Experiments and Theory
Thermoplasticity deals with the interaction between temperature, stress and plastic deformation due to either a stress increment, or a temperature change, or to a combination of a stress increment and a change in temperature. As in the case of isothermal plasticity the concepts of the yield surface and of the plastic strain rate are of fundamental importance. The yield surface and the plastic strain rate are now functions of the temperature in addition to being functions of the other variables which appear in isothermal plasticity.
