On notch and crack size effects in fatigue, Paris’ law and implications for Wöhler curves	2018	15	.pdf	application/pdf	8123	359	59	Paris’ law The second important power law in fatigue is Paris’ law, giving the advancement of fatigue crack per cycle, va, as a function of the amplitude of stress intensity factor ΔK (see Fig.2) In the former case, in the presence of a crack it is useful to design for fatigue crack propagation (like in the “damage tolerance” design approach), because the static limit is very high and the threshold condition is perhaps too strict, and there is margin to gain from a more elaborate design.	cache/fis-2009.pdf	txt/fis-2009.txt
