A Simple Fracture Mechanics Based Method for Fatigue Life Prediction in Thick-Walled Cylinders

Abstract

A method is proposed for predicting the fatigue life of thick-walled cylinders based on numerical integration of the fatigue crack growth curve as determined from a fracture mechanics analysis. The effects of autofrettage residual stresses, crack shape, and of the compressive portion of the stress intensity factor are accounted for. A method for correcting the autofrettage residual stresses for the Bauschinger Effect, based on recent analytical results by Peter Chen, is also included. A simple computer program for performing the calculation of fatigue life is presented along with a comparison of the calculated results with the experimental results of Davidson, and of Throop and Fujczak.
