Methodes for Fatigue Life Prediction

Methodes for predikting fatigue life cen be broadli kategorized into experiencentol, analiticál, and numerical approaches. Each method offers differt prefecages depending on the application and d applicable data.

Kísérleti metodok

Kísérlet a teing involves substanting material sampes or structura al concents to cyclic loading to observe fallure points. Tiss provides direct data but can be costilly and time-consumming.

Analytical Methods

Analytical approaches use matematycel models to estimate fatigue life based on material properties, stres analysis, and loading conditions. S- N curves are companly used ith this context.

Numericál Method

Numericál method, such a s finite element analysis (FEA), simulate stres distributions and predikt fatigue life underr complex loading informos. These methodes are widely used id in modern regionin design.
