Effects of Residual Stress on Fatigue Crack Propagation

摘要: Experimental results on the effects of compressive and tensile residual stresses on Mode I fatigue crack growth are briefly reviewed. Prediction methods that attempt to account for the observed effects are compared. Current limitations of the methods and their relative advantages and drawbacks for use in design analysis are discussed. The possible role of residual stress re-equilibration on growth behavior, caused by crack extension itself, is also discussed.
