Linear Thermomechanical Coupling Effect in Transient Deformatin,

Abstract

The interaction between the quasi-static mechanical deformation and the thermal state of solids is studied. Principles of classical thermodynamics are used to calculate temperature changes arising from the isentropic deformation of elastic solids. The theory of irreversible thermodynamics is used to predict temperature changes due to the adiabatic deformation of viscoelastic solids. It is found that such temperature changes are small and that the effect of thermomechanical coupling may usually be neglected in the non-oscillatory deformation of linear elastic, finite (rubber) elastic, and linear viscoelastic solids. Data are presented for several metals, rubbers, and plastics. Dynamic processes are not considered.
