Numerical Modeling of Fretting Fatigue Crack Nucleation using Finite Element Method, M.Sc. Thesis Sharif University of Technology ; Adibnazari, Saeed (Supervisor)
Abstract
Fretting fatigue damage occurs in contacting components while they are subjected to fluctuating loads and relatively small movement at the same time. In this condition some micro-cracks are created in these components. These micro-cracks will be propagated and cause sudden failure which is accompanied by great human and economic loss. There are many practical applications that are subjected to fretting fatigue, such as bolted and riveted connections, bearing shafts, blade-disk attachment in gas turbines, aero-engine splined couplings, cable connections and etc. Fretting fatigue failure process can be divided into two portions of crack initiation and propagation. It is very difficult, to...
