RESUMO

This work deals with the structural analisys of problems involving mechanical fatigue using the Finite Element Method and Software Engineering concepts. Initially, the basic concepts of mechanical fatigue, the conventional design techniques and the major research areas are reviewed. The material constitutive model to treat the fatigue process is developed based on Damage Mechanics and the numerical solution for the equilibrium equation is obtained by the Finite Element Method. The results obtained with the implementation of the constitutive mo deI and for structural analisys have good agreement with the literature references. All the computational programs are implemented using the concepts of Software Engineering. As example of the application of these concepts, a graphical environment for finite element mesh generation is developed based on third party software components
