An Application of Fracture Concepts to the Prediction of Critical Length of Fatigue Cracks. Part IV. Fracture Mechanics Analyses for Prediction of Critical Lengths and Velocities of Fatigue Cracks in 7075-T7351 Aluminum Alloy

摘要

The Irwin fracture criteria and Boyle mechanical compliance analysis were used to predict critical crack lengths of stable fatigue cracks in aluminum alloy (7075-T7351) plates. The Boyd hypothesis was also used to predict the velocity of unstable cracks in these plates. (Author)
