Effect of Specimen Thickness and Stress Intensity Factor Range on Plasticity-Induced Fatigue Crack Closure in A7075-T6 Alloy

Effect of Specimen Thickness and Stress Intensity Factor Range on Plasticity-Induced Fatigue Crack Closure in A7075-T6 Alloy

Fatigue crack growth experiments are performed using A7075-T6 compact tension (CT) specimens with various thicknesses <i>t</i> (1-21 mm). The stress intensity factor at the crack opening level K<sub>op</sub> is measured, and the effects of <i>t</i> and the stress...
