Effects of Residual Stresses on Stress-Corrosion Crack Growth Rates in Aluminum Alloys

摘要

Stress-corrosion crack growth rate data obtained as a function of the plane-strain stress intensity using double cantilever beam specimens of 7079, 7075, and 7175 are presented. The effects of quenched-in residual stresses on crack growth rates in specimens of this design are discussed, and methods of eliminating the residual-stress problem are presented. (Author)
