Thermal Analysis of a FGM Coated Composite with Imperfect Contact under High-Temperature Exposure

Ceramic coatings work as a tool to protect the material from excessive heat or any other rough exposure.Composites with coatings of functionally graded materials are becoming very popular with their very useful thermo-mechanical properties.In this study, a steady state thermal analysis is performed on a composite having two layers, one with the homogeneous substrate and the second is FGM coating under high-temperature exposure of the top of the surface.The numerical examples taken are having cracks along interfaces that produce discontinuities in temperature as well as flux.A decomposed immersed interface method is applied for obtaining the solution of the considered numerical examples which incorporates various types of discontinuity along the crack.
