Title

Simulations Mapping Stress Evolution In High Temperature Ceramic Coatings Under Thermal-Mechanical Conditions

Abstract

Finite element simulations representing thermal barrier coatings on turbine blades enabled mapping of the stress evolution within the multi-layer configuration under thermalmechanical conditions. The study aims to accurately model the transient strain behavior throughout a load cycle due to plasticity, creep, and oxide growth. The results were compared with in-situ experimental quantitative measurements performed previously using synchrotron X-ray diffraction. The studies verify the stress within the thermally grown oxide for critical combinations of temperature and load. These numerical models can be used to predict in-cycle stresses that lead to eventual failure of the coatings. © 2013 by the American Institute of Aeronautics and Astronautics, Inc.
