Advances in Mechanical Engineering, 2019 To overcome the limitation of constant Poisson’s ratio in bond-based peridynamics, an ordinary state-based peridynamic (OSB PD) model was applied to simulate dynamic crack propagation in Kalthoff–Winkler specimen subjected to a low velocity impact.

Surface Crack Shape Evolution Modelling using an RMS SIF approach [PDF]
, 2010 The majority of fatigue cracks in thick plate and tubular sections in structural components are two-dimensional surface cracks having significant propagation lives before becoming critical.

A numerical study of crack shielding and deflection under extensive plasticity [PDF]
, 2009 Experimentally observed crack deflection events in multi-layered material systems, occurring even under pure mode-I loading, are here simulated and explained through elasto-plastic finite element modelling.

A new approach for the influence of residual stress on fatigue crack propagation
Results in Physics, 2017 Many manufacturing processes can induce residual stresses in produced components. These residual stresses influence the mean stress during cyclic loading. The initial residual stresses induced during manufacturing change during fatigue damage. This paper

Fatigue crack growth behaviour and life prediction for 2324-T39 and 7050-T7451 aluminium alloys under truncated load spectra [PDF]
, 2010 This paper presents a study of crack growth behaviour in aluminium alloys 2324- T39 and 7050-T7451 subjected to flight-by-flight load spectra at different low- stress truncation levels. Crack branching was observed in the higher truncation levels for the

Size effects on residual stress and fatigue crack growth in friction stir welded 2195-T8 aluminium - Part I: Experiments [PDF]
, 2011 Residual stress fields were measured in three different sizes of Compact-Tension (C(T)) and eccentrically loaded single edge notch (ESE(T)) specimens containing transverse or longitudinal welds. The effect of size on residual stress profiles was studied.

Evaluation of the intrinsic crack growth rates of weld joints [PDF]
, 2011 A method is presented for evaluating weld intrinsic fatigue crack growth rate (FCGR) by excluding the influence of residual stresses. The method is potentially useful for predicting crack growth lives of structural components using measured FCGR data ...
