Transient thermoelastic analysis for a multilayered thick strip with piecewise exponential nonhomogeneity

This paper is concerned with the theoretical treatment of transient thermoelastic problem involving a multilayered thick strip with piecewise exponential nonhomogeneity due to nonuniform heat supply in the width direction. The thermal and thermoelastic constants of each layer are assumed to vary exponentially in the thickness direction, and their values continue on the interfaces. We obtain the exact solution for the two-dimensional temperature change in a transient state, and thermoelastic response of a simple supported strip under the state of plane strain. Some numerical results for the temperature change, the displacement and the stress distributions are shown in figures.
