TL;DR: In this paper, a study of the influence of load ratio R on fatigue crack propagation behavior and specifically on the value of the fatigue crack growth threshold, Δ K 0, in a bainitic 2.25 Cr-1Mo pressure vessel steel tested at 50 Hz in aqueous, and moist and dry gaseous environments.

Abstract: An investigation of fatigue crack growth of interfacial cracks in bi-layered materials using the extended finite element method is presented. The bi-material consists of two layers of dissimilar materials. The bottom layer is made of aluminium alloy while the upper one is made of functionally graded material (FGM). The FGM layer consists of 100 % aluminium alloy on the left side and 100 % ceramic (alumina) on the right side. The gradation in material property of the FGM layer is assumed to be exponential from the alloy side to the ceramic side. The domain based interaction integral approach is extended to obtain the stress intensity factors for an interfacial crack under thermo-mechanical load. The edge and centre cracks are taken at the interface of bi-layered material. The fatigue life of the interface crack plate is obtained using the Paris law of fatigue crack growth under cyclic mode-I, mixed-mode and thermal loads. This study reveals that the crack propagates into the FGM layer under all types of loads.

Journal ArticleDOI
TL;DR: In this article, a number of modifications to the Wheeler fatigue crack retardation model were proposed to account for the delay retardation due to applied overloads, initial crack growth acceleration immediately following an overload, overload interaction and the net section yielding effect observed in the fatigue crack growth retardation behaviour of many materials.

TL;DR: In this paper, the authors investigated the fatigue crack growth behavior of cracked aluminum plate repaired with bonded composite patch especially in thick plate and determined the stress intensity factor of patched crack from experimental result by comparing the crack growth behaviour of specimens with and without repair.
