Abstract

Abstract

The problem considered here is the response of a substrate/coating structure subjected to dynamic heating. By utilizing Laplace transform and Fourier transform technique, the general solutions for temperature fields and stress fields are derived. The dynamic thermal stresses are presented under different heating rates for various substrate and coating thicknesses. The possible failure mode and the optimized coating thickness are analyzed.
