Resumo:
This work aims to analyze and study the material fatigue. Numerical analyzes are made for SN models (stress-life), which depart from simplifications for cases that are closer to the actual model. The effects of parameter changes in the part and in the loading will be observed on numerical results in fatigue. In the case of uniaxial fatigue shall be presented examples of complex loads, which will be addressed by the traditional technique of counting cycles, the Rainflow method. Combined loading will also be treated, extending the work to the study of multiaxial fatigue.
