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 ...

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 ...

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 ...
