Fatigue-Crack Propagation and Residual Static Strength of PH 15-7 Mo (TH 1050) Stainless Steel

Abstract

Fatigue-crack propagation and residual static-strength data from tests on 2-inch (5.1-cm) wide sheet specimens made of PH 15-7 Mo (TH 1050) stainless steel are presented in this report. In addition, the capabilities of McEvily and Illg's crack-growth analysis and Kuhn and Figge's residual strength analysis to correlate the test data have been investigated. Kuhn and Figge's equation for calculating the stress concentration factors for cracks was used in both analyses. Analysis of the data showed that the crack growth and residual strength analyses satisfactorily correlated the majority of the test data.
