Fatigue Crack Initiation and Propagation
TypeChapitres d'ouvrages scientifiques
The resistance of metal alloys to fatigue can be classified into four major regimes: low-cycle fatigue (or short life), limited resistance (between 10^5 and 10^6 cycles), high-cycle fatigue (between 10^6 and 10^7 cycles) and gigacycle (more than 10^7 cycles). This chapter introduces the basic concepts of cyclic mechanical behavior, crack initiation and propagation in these different regimes.

Non-local energy based fatigue life calculation method under multiaxial variable amplitude loadings SAINTIER, Nicolas; PALIN-LUC, Thierry; BÉNABÈS, Jérôme; COCHETEUX, Francis (Elsevier, 2013)Reliable design of industrial components against high cycle multiaxial fatigue requires a model capable of predicting both stress gradient and load type effects. Indeed, taking into account gradient effects is of prior ...
About the effect of plastic dissipation in heat at the crack tip on the stress intensity factor under cyclic loading RANC, Nicolas; PALIN-LUC, Thierry; PARIS, Paul C.; SAINTIER, Nicolas (Elsevier, 2013)Because of the reverse cyclic plastic zone at the crack tip, there is plastic dissipation in heat at the crack tip under cyclic loading. That creates a heterogeneous temperature field around the crack tip. A thermo-mechanical ...
