A steel rod contains a crack length of 3mm. The steel has a coefficient of m=4 and c=10^-11 when deltasigma is in MPa , and the Y factor for this geometry is 1.2m how long will the crack take to grow by fatigue to a length of 10mm, under an applied stress amplitude of 60MPa? It asks me to get an answer close to one of the 6 stated answers. I have 5500 cycles(adsbygoogle = window.adsbygoogle || []).push({});
