Abstract
In this paper, the element free Galerkin method has been used to model and simulate the fatigue crack growth phenomenon in cracked specimens containing material discontinuities like holes and bi-material interfaces. The appropriate enrichment functions are added to the standard EFGM approximation in order to take into account the effect of various discontinuities present in the domain. The level set method is used to track different discontinuities present in the domain. Finally, several numerical problems are solved to demonstrate the effect of these material discontinuities on fatigue crack growth.
