The formulation of the symmetric Galerkin BEM for 3D elastic fracture mechanics problems and some relevant computational aspects are presented in this paper; the method is employed for the evaluation of stress intensity factors and for the modeling of fatigue crack growth. In the latter context a propagation algorithm has been developed and implemented into a fully automated numerical code which is used to analyze two example problems concerning the fatigue growth of surface breaking cracks.
