Crack Propagation Analysis of Compression Loaded Rolling Elements

Popis výsledku v původním jazyce

The problem of crack propagation from internal defects in thermoplastic cylindrical bearingnelements is addressed in this paper. The crack propagation in these elements takes place undernmixed-mode conditions—i.e., all three possible loading modes (tensile opening mode I and shearnopening modes II and III) of the crack are combined together. Moreover, their mutual relation changesnduring the rotation of the element. The dependency of the stress intensity factors on the crack lengthnwas described by general parametric equations. The model was then modified by adding a voidnto simulate the presence of a manufacturing defect. It was found that the influence of the void onnthe stress intensity factor values is quite high, but it fades with crack propagating further from thenvoid. The effect of the friction between the crack faces was find negligible on stress intensity factornvalues. The results presented in this paper can be directly used for the calculation of bearing elementsnlifetime without complicated finite element simulations
