Abstract
Content

A methodology for predicting stresses and the resultant cracking in plasma-sprayed thermal-barrier coatings (TBCs) has been developed. The methodology is built around a computer code that implements a finite-element model that simulates the evolution of stresses, strains, and related phenomena in a TBC. The economic and technological value of the methodology lies in its potential to provide a more systematic basis for designing reliable and durable TBCs for advanced gas turbine engines by reducing the amount of time-consuming empirical testing needed to assess alternative TBC designs.
