Fatigue of Metals
Pedro Peralta,Campbell Laird +1 more
TL;DR: In this article, the three fundamental aspects of metal fatigue are reviewed, namely cyclic deformation, crack nucleation and crack propagation, with emphasis on experiments and modeling of pure cubic and hexagonal metals and their alloys for low, high and very high cycle fatigue regimes.

Low cycle fatigue life prediction in shot-peened components of different geometries – Part II: Life prediction
TL;DR: In this article, the effects of shot peening on the low-cycle fatigue (LCF) performance of a low pressure steam turbine blade material were investigated. And the application of this model has been extended to different notched geometries in this study.

Life assessment methodologies incoroporating shot peening process effects: mechanistic consideration of residual stresses and strain hardening Part 2 – approaches to fatigue lifing after shot peening
TL;DR: In this article, the effects of the shot peening process on component fatigue life were investigated. But, the authors focused on the effect of shot peeling on the quality of component fatigue.

Effects of Axial and Multiaxial Variable Amplitude Loading Conditions on the Fatigue Life Assessment of Automotive Steering Knuckle
TL;DR: One of the major achievements of this study is that for the components with complex geometry and under multi-input loading like the steering knuckle, it is essential to perform fatigue analysis by considering all real conditions and cannot be only focused to the destructive loading.

Prediction of fatigue damage region with the use of the notch critical plane approach for crack initiation and propagation
TL;DR: In this paper, a new approach is proposed to distinguish crack initiation and propagation stage by notch critical plane (NCP) approach, which is the plane which passes through the fatigue critical point (FCP) and undergoes the maximum shear stress amplitude.

Strain-energy-density factor applied to mixed mode crack problems
TL;DR: In this paper, the authors investigated the general problem of crack extension in a combined stress field where a crack can grow in any arbitrary direction with reference to its original position, and showed that the direction of crack growth and fracture toughness for the mixed problem of Mode I and Mode II are governed by the critical value of the strain-energy-density factor.

A review of some plasticity and viscoplasticity constitutive theories
TL;DR: In this paper, the main ingredients and assumptions of developing macroscopic inelastic constitutive equations, mainly for metals and low strain cyclic conditions, have been discussed, with some comparisons with the previous ones, including more recent developments that offer potential new capabilities.
