Simulation of fatigue crack propagation under contact loading conditions
Original language description
Numerical simulations of pitting arise phenomena on the gear teeth is presented in the article. The presented approach is based on the assumption that pitting (pits) are a result of fatigue crack propagation under complex (rolling, sliding, lubricated) contact loading conditions. The solution approach consisted of numerical simulations of fatigue cracks growth in the FEM framework. Penetration of the fluid lubricant into fatigue (pitting) cracks is simulated using special cavity finite elements, which allow to include so called lubricant closure inside crack. Fatigue (pitting) crack growth predictions are based on the Paris law in conjunction with FEA of fracture criteria. The simulations were carried out under the commercial code ABAQUS CAE FEM programme which allows to develop in-house codes using the Python scripting language and which is the basis of all FEA including the simulation of the contact loading conditions and the crack growth. An acceptable agreement of the numerical and
