Resumen:
The use of fracture mechanics based methodologies to assess the influence of defects on the high cycle fatigue resistance of mechanical components has become increasingly important for industrial applications and design. This presentation introduces the most commonly used fracture mechanics methods, emphasizing the assumptions on which they are based and analyzing their potential in predicting the influence of the main geometrical, mechanical and microstructural variables involved in the definition of the fatigue resistance of the components. Underlying hypotheses are discussed thoroughly and possible directions for future research are suggested. Ap- plications examples on different configurations with small defects are presented. Finally, the potential of the fracture mechanics methodologies is analyzed when proposing simplifications suitable for use in the develop- ment of design documents for engineering applications.
