EVAPRED - A CODE FOR FATIGUE ANALYSIS OPTIMIZATION

Journal Title: INCAS BULLETIN - Year 2010, Vol 2, Issue 1

Abstract

The fatigue can be, in fact, defined as: “failure under a repeated or otherwise varying load, which never reaches a level sufficient to cause failure in a single application”. Physical testing is clearly unrealistic for every design component. In most applications, fatigue-safe life design requires the prediction of the component fatigue life that accounts for predicted service loads and materials. The primary tool for both understanding and being able to predict and avoid fatigue has proven to be the finite element analysis (FEA). Computer-aided engineering (CAE) programs use three major methods to determine the total fatigue life: Stress life (SN), Strain life (EN) and Fracture Mechanics (FM). FEA can predict stress concentration areas and can help design engineers to predict how long their designs are likely to last before experiencing the onset of fatigue.
