Sažetak
The paper presents a computational model for the simulation of surface initiated fatigue crack growth on contacting mechanical elements as used in gears, bearings, etc. A simple equivalent model of two cylinders is used for simulation of fatigue crack growth under conditions of rolling and sliding contact. The equivalent model is subjected to the normal and tangential contact forces which also take into account the influence of EHD-lubrication conditions as well as the associated lubricant pressure acting on the crack faces. The VCE method in the framework of FEA is used for simulating the fatigue crack propagation from the initial crack up to the formation of the surface pit.
