The fretting wear behaviour of Ti–6Al–4V is experimentally investigated using a cylinder-on-flat specimen arrangement for different loads, strokes and numbers of fretting cycles, including partial slip and gross sliding conditions. An elastic–plastic, finite element (FE) based, incremental wear simulation approach is employed to study the evolution of the surface and sub-surface fretting variables,...
Previous studies by the authors have developed finite element (FE) based approaches to simulate fretting wear by material removal without consideration of the effects of debris. It was assumed that, wear particles, once generated, were immediately removed from the fretting interfaces and disappear. This method calculates the local wear as a function of local contact pressure and local slip, and incrementally...
The prediction of fretting wear is a significant issue for the design of high-performance aeroengine spline couplings, due to the potential for slip between the highly loaded spline teeth under cyclic loads. The work reported here aims to demonstrate the feasibility and difficulties of applying a finite element based fretting wear simulation tool, which incrementally updates the contact geometry with...
A finite element-based method is presented for simulating both the fretting wear and the evolution of fretting variables with number of wear cycles in a cylinder-on-flat fretting configuration for application to aeroengine transmission components. The method is based on a modified version of Archard's equation and is implemented within a commercial finite element code. Fretting tests are employed...
