fis-1491	Antunes, F.V.; Branco, R.; Correia, L.; Ramalho, AL	A numerical study of non-linear crack tip parameters	2015	10	.pdf	application/pdf	5790	265	61	[35] Paul, S.K., Tarafder, S., Cyclic plastic deformation response at fatigue crack tips, Int Journal of Pressure Vessels and Piping, 101 (2013) 81-90. It was demonstrated that: i) LEFM concepts are applicable to the problem under study; ii) the crack closure phenomenon has a great influence on crack tip parameters decreasing their values; iii) the Keff concept is able to explain the variations of crack tip parameters produced by the contact of crack flanks; iv) the analysis of remote compliance is the best numerical parameter to quantify the crack opening level; v) without contact there is no effect of stress ratio on crack tip parameters.	cache/fis-1491.pdf	txt/fis-1491.txt
