Capítulo IPEN-doc 27683 Crack propagation in the threshold stress intensity region a short review2019 - RICARDO, LUIZ F.F.; TOPPER, TIMOTHY H.; RICARDO, LUIZ C.H.; MIRANDA, CARLOS A.J.This work presents a short review of fatigue crack propagation with emphasis on the parameters that influence the threshold stress intensity, ΔKth. This threshold value is dependent on such variables as the material itself, the test conditions, the R-ratio, the environment and crack closure. The crack geometry effects are discussed as well as some crack closure models. A discussion of other parameters that influence the threshold stress intensity regime including short crack thresholds and their respective models and their application will be the subject of a near-future review.Artigo IPEN-doc 22415 Influence of the crack propagation rate in the obtaining opening and closing stress intensity factor by finite element method2016 - RICARDO, LUIZ C.H.; MIRANDA, CARLOS A.J.Artigo IPEN-doc 21768 Crack simulation models in variable amplitude loading - a review2016 - RICARDO, LUIZ C.H.; MIRANDA, CARLOS A.J.
