Fatigue Crack Propagation and Load Interaction Effects in a Titanium Alloy

摘要: An experimental investigation of load interaction effects in Ti-6Al-2Sn-4Zn-2Mo is presented. Simple variable amplitude loading spectra were applied to test samples, and the crack propagation stress intensity factor, K P R , was subsequently measured. The data condensed two equations ("master curves") that describe influence an unloading cycle after constant a single overload cycle, respectively. results suggest are caused by residual compressive stresses ahead front, whereas closure minor.
