Coupled thermoviscoplasiicity equations for materials with temperature-dependent material properties are developed based on the rational theory of thermodynamics. It is shown that, in addition to the mechanical work due to viscoplasticity, micro-structural effects, and dilatation, a mechanical work due to the temperature dependency of the material properties contributes to the total rate of mechanical energy generation. Axisymmetric cyclic bending of a circular plate with a hole clamped at the inner edge has been solved, using fmite~element analysis, in order to investigate the effect of coupling and the temperature-dependent material properties on the thermomechanical behavior of the plate. For the material chosen (steel 1070) and under the conditions considered (infinitesimal deformation and constant ambient temperature), the effect of coupling as well as the contribution of the temperature-dependent material properties is negligible. |
