Fretting fatigue is a degrading process which responsible for considerable amount of mechanical structure failure every year. In the present study, finite element model proposed to show effect bending moment on flat surface under fretting loading. The results that has major friction stress distribution two solids contact. Finite analysis predicts an increased damage when load applied as pure mo...

The performance characteristics of metal matrix composites (MMCs) and the need to study their fretting fatigue wear during service are discussed. Four main elements MMCs (aluminum, copper, titanium, iron, magnesium, nickel, etc.) These factors influencing fatigue, mechanism research, life prediction, development process protection methods, respectively. Factors such as internal crack nucleation...

Looking at wear of incomplete contacts in partial slip we start from an asymptotic description the contact tractions edges. We introduce distributed dislocations along zone to account for profile reduction due and find long-term time asymptote where is wholly stuck. The resulting stress field used crack tip intensity factors short edge cracks, which are useful predicting nucleation threshold.

The number of revision total hip arthroplasties is predicted to more than double in USA over the next 25 years from an estimated 40800 in 2005 to approximately 96700 in 2030 [1]. Modular femoral stems offer the advantage of adjustment and restoration of joint kinematics including leg length, femoral version and offset, regardless of the exact position of the distal part of the stem [2]. Disadva...

Submarine power cables (SPC) are vulnerable to fretting, wear, and fatigue due the dynamic environment, particularly at end connectors junctions or other discontinuities, such as seabed features. This paper presents a finite element methodology for global local analysis of fretting between copper conductors in multi-strand cables. The salient inter-wire variables, relative slip contact pressure...
