Advanced FE model for simulation of pitting crack growth

Popis výsledku v původním jazyce

An advance parametric FEA model for simulation of pitting arise phenomena on the gear teeth is presented in this article. The assumption of the developed computational approach was that pitting (pits on the contact surfaces) is a result of fatigue crackpropagation under (rolling) contact loading conditions. Developed crack growth laws (based on the Paris law) allow to perform simulations of pitting crack growth with respect to the non-proportional and non-linear nature of loading of pitting crack tip,which result from specific loading condition. Specific crack tip loading and pitting crack growth was evaluated using the J-integral criterion of fracture mechanics. Advance model of penetration of the fluid lubricant into fatigue (pitting) cracks was designed using special hydrostatic fluid finite elements, which allow to include the closure of pressured lubricant between fracture surfaces during the simulation of gearing meshing. A simplified distribution of residual stresses in the su
