Railway axle reliability is paramount to ensuring the safe operation of modern trains. Recent studies have focussed on understanding fatigue behaviour and crack propagation mechanisms in axle ...

Researchers have developed a simplified mathematical model (step-loading model, SLM) that unifies two earlier mechanisms to describe the velocity jump in crack propagation. Through SLM, they showed ...

This paper presents a summary of the recent developments in fatigue analysis. It is pointed out that fatigue is a consequence of cyclic plasticity and that local stress and strain provide the ...

Research physicists have developed large-scale computer simulations to analyze how cracks form and grow in materials including steel, glass, nanostructures, and human bone. Crack-propagation analysis ...
