Effect of Notch on Low Cycle Fatigue of AA 2024-T351
Abstract: Notch effect on low cycle fatigue of AA 2024-T351 was investigated. Decreasing notch curvature leads to less cyclic hardening. Values of fatigue strength exponent (b) and fatigue ductility (c) for notch specimens were out of range of metallic materials. The SEM examination showed multi-crack origins with secondary cracks and a large final-fracture zone for unnotched specimens, while there was small final fracture zone close to the center of the specimen …

Phase – Field Modeling of Brittle and Ductile Fracture Under Complex Loading Conditions
Abstract: Phase-field modeling has emerged as a powerful computational framework for predicting fracture behavior in engineering materials, offering a unified description of crack initiation, propagation, branching, and coalescence without the need for explicit crack tracking. This study presents an in-depth examination of phase-field modeling applied to both brittle and ductile fracture under complex loading conditions, including multiaxial stress states, cyclic loading, thermal gradients, and dynamic impact. The phase-field approach regularizes the …
