Strip yield modelling of fatigue crack under variable amplitude loading
The results from ‘strip yield’ approach of the FASTRAN type models of plasticity induced crack closure effects of fatigue cracks subjected to variable amplitude loadings are presented. The strip yield results are compared with authors’ finite element (FE) and experimental results. It has been observed that the strip yield model is seen to be fundamentally limited by choice of α (constraint fact...
متن کاملAnalyses of Fatigue and Fatigue-crack Growth under Constant- and Variable-amplitude Loading
Studies on the growth of small cracks have led to the observation that fatigue life of many engineering materials is primarily “crack growth” from micro-structural features, such as inclusion particles, voids, slip-bands or from manufacturing defects. This paper reviews the capabilities of a plasticity-induced crack-closure model to predict fatigue lives of metallic materials using “small-crack...

متن کاملPrediction of fatigue crack growth under constant amplitude loading and a single overload based on elasto-plastic crack tip stresses and strains
It is generally accepted that the fatigue crack growth (FCG) depends mainly on the stress intensity factor range (DK) and the maximum stress intensity factor (Kmax). The two parameters are usually combined into one expression called often as the driving force and many various driving forces have been proposed up to date. The driving force can be successful as long as the stress intensity factor...
متن کاملTransient Fatigue-crack Growth Behavior following Variable-amplitude Loading in a Monolithic Silicon Nitride Ceramic
ÐTransient cyclic fatigue-crack growth behavior following variable-amplitude loading sequences has been investigated in a hot-pressed, monolithic Si3N4 ceramic (NTK EC-141), for which fracture toughness (resistance-curve) and cyclic fatigue properties are well characterized. Following rapid changes in the applied stress-intensity range, DK, during both low-high and high-low block-loading sequen...
