Application of Fracture Mechanics at Elevated Temperatures.

Abstract

The applicability of linear elastic fracture mechanics to predict crack growth at elevated temperatures is investigated. The interactive effects of stress, temperature, time, and environment on the crack growth of an advanced gas turbine disk alloy, IN-100, are discribed with an interpolative empirical model based on the hyperbolic sine.
