Researchers establish a high-throughput multiscale evaluation method for thermal stress in thermal barrier coatings

Researchers at Kunming University of Science and Technology have developed a high-throughput multiscale method to evaluate thermal stress in thermal barrier coatings (TBCs), essential for gas turbines. This new method integrates first-principles calculations with finite element simulations to assess the phase transitions in ceramic layers, which significantly impact thermal stress distribution. The approach not only improves the accuracy of thermal stress measurement under varying temperatures but also aids in optimizing the materials’ design for better durability and efficiency in high-temperature environments.
