WebAlthough no stable cracking was seen in the par- tially or fully crystalline structures, the amorphous alloy was susceptible to fatigue-crack growth under cyclic loads; be- havior in terms of fractography and the dependency of growth rates on the stress-intensity range is similar to tradi- tional crystalline metals. WebParis' 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 the load …
