For this reason fatigue cracks spend most of their life as very small cracks which are hard to detect. A new approach for the simulation of fatigue crack growth in two elastic materials has been developed and specifically, the concept has been applied to fretting fatigue in a straight plate and in tubular joints. In the proposed method, the formation of new surface is represented by an interface element based on the interface potential energy. This method overcomes the limitation of crack growth at an artificial rate of one element length per cycle. In this method the crack propagates only when the applied load reaches the critical bonding strength. The predicted results compares well with experimental results.
