Coupled Thermomechanical Analyses for Thermal Shock of Ceramic/Metal Gradient Thermal Barrier Coatings

摘要：

　　A coupled and uncoupled non-linear thermomechanical finite element analysis using ANSYS have been carried out to analyze the heat transfer and associated thermal stresses during different simulated thermal shock processes,and the results of two analyses are discussed.It indicates that piezocaloric effect can be neglect when thermal shock intensity is mild and piezocaloric effect should be taken into account when thermal shock intensity is severe.
