Surface fatigue crack growth under EHD lubrication conditionsFajdiga, Gorazd ; Flašker, Jože ; Glodež, SrečkoThe paper describes a two-dimensional computational model for the simulation of surface initiated fatigue crack growth in the contact area of gear teeth flanks. The discretised model of gear teeth is ... subjected to normal loading (Herzian contact pressure), tangential loading (friction between gear teeth flanks) and additional external contact forces that arise from the EHD lubricating conditions. The J-integral method in the framework of the finite element analysis is used for simulation of the fatigue crack propagation from the initial to the critical crack length, when the surface material layer breaks away and pit appears on the surface. The comparison of computational and experimental results shows that the proposed model reliably simulates the surface fatigue crack growth under contact loading and can be used for computational predictions of surface pitting for various contacting mechanical elements like gears, bearings, wheels, etc.Vir: Damage and fracture mechanics VI : computer aided assessment and control (Str. 71-82)Vrsta gradiva - prispevek na konferenciLeto - 2000Jezik - angleškiCOBISS.SI-ID - 5362198
