Experimental and numerical solutions of contact fatigue


Abstract eng:
This article shows: 1. Some studies of a low-cycle material fatigue caused by cyclical contact between two spheres with the same diameters. The spheres are made up from modified 15219 steel. The problem was solved by FEM (SW MSC.MARC/Mentat. The results show hysteresis loops from which the number of cycles until fracture can be determined. 2. The realisation of test device for the research of contact fatigue as complement of the loading test machine INOVA, which is directed to look for quantitative coherence between number of cycles to the origin of fatigue cracks in the area of mechanical contact.
