Numerical Modeling Issues in Finite Element Simulation of Plasticity Induced Crack Closure With an Emphasis on Material Model Effects
Plasticity induced crack closure (PICC) has a potentially strong effect on the growth rate of fatigue cracks in metal structures. As a crack grows through previously yielded material, the permanent deformation in the crack wake Shields the crack tip from the full impact of the remote load. This …

Theoretical and experimental modelling of multiple site damage in plate components.
… damage (MSD), such as two or more interacting cracks, currently represents a challenging problem. The lifetime prediction of structural components with MSD is still largely based on 2D single crack solutions available in various handbooks or derived from the simplified finite element analysis. …

Non-linear individual and interaction phenomena associated with fatigue crack growth.
… a new approach for the analysis of fatigue crack growth, known as damage tolerant design. This approach utilises fracture mechanics principles to consider the propagation of fatigue cracks from an initial crack length until final fracture, or a critical crack length, is reached. Since the …

Effect of Variable Amplitude Loading on Fatigue Crack Growth Rate
Fatigue crack growth (FCG) is a major cause of failure in many engineering component and structure that are subjected to dynamic loading conditions. Several models have been proposed for estimating crack growth rate da/dN under various conditions. The majority of work reported has focused on …

The Effects of Load Ratio on Threshold Fatigue Crack Growth of Aluminum Alloys
… structures are threatened by the presence of cracks. Structural failure occurs if a crack larger than a critical size exists. Although most well designed structures initially contain no critical cracks, subcritical cracks can grow to failure under fatigue loading, called fatigue crack growth …
