Description

This lecture covers the concept of fatigue in materials, focusing on stress amplitude and endurance limit. It explains how materials behave under cyclic loading, the number of cycles to failure, and the impact of stress on fatigue. The instructor discusses empirical laws, crack propagation mechanisms, and the influence of stress intensity factor on fatigue. Practical examples such as wheel-rail contact and airplane engine stress are also explored.
