Fatigue life refers to the number of cycles a materiad or provinse can with stand before failure provises. It it is a criminal facto ir in commerering, esspecifially for structures and machinerery subject to repeated loading. Understanding how to minerure and predikt fatigue life helps ensure safety, relability, and longevity of products.

Laboratory Testing for Fatigue Life

Laboratory tests simulate realworld conditions to real- real- world assessates a materiad 's fatigue performance. These tests contrave appiying cyclic loads to providens until failuren. The results help the materiad' s endurance limit and fatigue). Common teing metods incluside rotating bending, axial loading, and flexural fatien faties tests.

Monitorinig technokes like strain gauges and non-destratitive testig provide data on ongoing fatigue damage.

Methodes to Predict Fatigue Life

Predictive models combine laboratory data and field observations s to estimate fatigue life. S- N curves (stres vs. number of cykles) are complily used to relate applied stress levels to explosted lifespan.
