Improvement Of Fatigue Prediction For Better Material Design

Fatigue represents the loss of a material's performance (mainly mechanical properties) under constant cyclic, or periodic, loading. In general, researchers only investigate the number of cycles until a failure under constant conditions, which are frequency and applied load amplitude (stress or strain). Over the years, researchers have proposed several models to predict the number of cycles until failure (N), but the most well-known and simple ones are the S-N or Wöhler curves. However, this analysis can only give information about...
