Description

This lecture covers the concepts of fatigue, fracture toughness, and material properties. It explains how cracks advance under stress, the stress intensity factor, and the relationship between plastic deformation energy and toughness. The instructor discusses the impact of stress amplitude changes on fatigue, Goodman's Rule for mean stress adaptation, and Miner's Law for cyclic stress. The lecture also delves into endurance limits, high and low cycle fatigue, and fatigue crack propagation mechanisms in ductile materials.
