Title: Fatigue and environmentally assisted crack propagation
Abstract: Paul C. Paris's analysis of fatigue crack growth using the linear elastic fracture mechanics concept is widely described to further explain the effect of the load ratio, the crack closure phenomenon, and their consequences on the fatigue crack growth behavior in metals. The Paris curves are used to explain the effect of the environment on the fatigue crack growth. Further, the effect of variable loads on fatigue crack growth and the use of Miner's rule are explained, as well as the effect of overload. The topic of fatigue crack emanating from holes is discussed along with an example based on the author's approach to assess the risk of forming a crack at a hole in a loaded panel. The mechanic characteristics of stress–corrosion induced crack propagation, creep crack growth, and crack growth by absorbed hydrogen are described. This last topic includes the description of a mathematical model of hydrogen-induced cracking derived by the author that agrees well with experimental observations.
