Fretting Induced Fracture of Coupling Driven Shafts
Failures of externally driven compressor crankshafts may sometimes be due to fretting induced fatigue cracks. Fretting is a degradation process which occurs between two faying surfaces where the relative motion between the components is very small. Discoloration, fine o~ide powder, and shallow surface pitting are the definitive signs of fretting and hence relative motion between components. Fra...
متن کاملOn the Convergence of Stresses in Fretting Fatigue
Fretting is a phenomenon that occurs at the contacts of surfaces that are subjected to oscillatory relative movement of small amplitudes. Depending on service conditions, fretting may significantly reduce the service life of a component due to fretting fatigue. In this regard, the analysis of stresses at contact is of great importance for predicting the lifetime of components. However, due to t...
متن کاملFretting Fatigue Experiment and Analysis of AlSi9Cu2Mg Alloy
An investigation was carried out in order to study the fretting fatigue behavior of an AlSi9Cu2Mg aluminum alloy. The fretting fatigue tests of AlSi9Cu2Mg were performed using a specially designed testing machine. The failure mechanism of fretting fatigue was explored by studying the fracture surfaces, fretting scars, fretting debris, and micro-hardness of fretting fatigue specimens using scann...
متن کاملFretting Fatigue Life Estimations Based on Critical Distance Theory
Fretting fatigue process have many features such as early stage crack initiation at contact edge, very slow crack propagation and fatigue failure after very long life operation. In this paper at first we present fretting fatigue model in high cycle region, which is considering the wear process near contact edge. And then we present fretting fatigue life estimation method in low cycle fatigue re...
متن کاملFatigue fracture of hydrogels
Rapid advances are taking place to develop hydrogels of high stretchability and toughness, but fatigue fracture has not been studied for any hydrogels. This negligence hinders the development of hydrogels and their applications. Herewe initiate a study of fatigue fracture of hydrogels.We choose polyacrylamide hydrogel as a model material. To place fatigue fracture in context, we apply monotonic...
