Description
Summary:Results are presented on the analysis of the effect of the thermomechanical coupling on the thermal response of an isotropic elastic beam subjected to a nonuniform temperature. Results illustrate the importance of properly accounting for thermomechanical coupling in computing the response of elastic solids subjected to abrupt heating. It is shown that beams of elastic isotropic solids reach equilibrium faster than predicted by the uncoupled theory, and that the use of the uncoupled theory overestimates the thermal stresses present before equilibrium is reached.
