WebParis' law. Typical plot of crack growth rate with respect to the stress intensity range where the Paris–Erdogan equation fits the central, linear region of Regime B. Paris' law (also known as the Paris–Erdogan equation) is a crack growth equation that gives the rate of growth of a fatigue crack. The stress intensity factor characterises ... WebAn R-Curve Assessment of Stable Crack Growth in an Aluminium Alloy 585 Sumpter [3] noted that crack extension in a large (b >> B) fracture test specimen was stable, whilst shallow cracks in small (b = B) specimens failed at maximum loads. However, crack growth in all high constraint geometries, whether large or small, initiated
