abstract
During recent years the development and application of linear elastic and viscoelastic fracture mechanics concepts have progressed to a point where they now provide a rational design and experimental approach to the problem of crack propagation. The paper presents the results of a study of the prediction of thermal tensile stresses using the theory of linear viscoelasticity, the application of fracture mechanics principles to an overlay, the development of an efficient and accurate computer code to utilize the thermal stresses to predict stress intensity factors, and the predicting of overlay life as a function of material properties and stress intensity factor.
