Numerical Analysis of EB-PVD Thermal Barrier Coatings under Thermal-Mechanical Coupled Environment

Abstract:

Article Preview

Numerical method was used to simulate the stress state of thermal barrier coatings (TBCs) under thermal-mechanical coupled environment. The finite element (FE) model was built as hollow tube and boundary conditions including heating rate, cooling air convection and mechanical loadings were considered. The maximum stress locates where maximum temperature gradients is formed. This failure mode is consistent with the experimental results.
