Abstract:In this paper, a review of some techniques proposed in the literature for modelling fretting wear is presented. Fretting wear occurs when surfaces are degraded and materials are removed due to a small relative oscillatory motion between two contact surfaces. Due to the continuous change in the shape of a structure during its lifetime, the design of engineering components subjected to fretting wear is a challenge to engineers and scientists. The available predictive tools in the literature, which make use of analytical solution of the contact pressure in the first cycle ignoring the wear effect and removal of materials in the subsequence cycles, provide inaccurate results. Numerical modelling techniques such as Finite Element Analysis (FEA) can be used to model any type of structures with configuration taking into account many complicated details such as large deformation, material non-linearity, change in geometry and time integration effect. Therefore, FEA is a very desirable technique for fretting wear analysis and lifetime prediction. This review covers modelling fretting wear using numerical modelling methods, which can be divided into three main techniques, namely the FEA method, Boundary Element Method (BEM) and Finite Discrete Element Method (FDEM). Keywords: Fretting wear, Finite Element Method, Contact mechanics INTRODUCTIONFretting wear is a phenomenon, in which surface degradations and removal of materials take place due to a small relative oscillatory motion and quasi-static load between two contact surfaces. There are many parameters that affect fretting wear including normal load, contact stress, frequency, slip amplitude, material properties, surface roughness of the contact bodies, etc. The design of engineering components subjected to fretting wear, such as couplings and splines, jointed structures etc.[1], is still a challenge to engineers. This is because of the continuous change in the component shape during fretting wear. Therefore, a predictive technique that takes into account the wear progress during life cycle is desirable. Analytical solutions of wear problems are very difficult and limited to simple 2-D configuration steady state analysis [2]. In contrast, numerical modeling techniques such as finite element analysis (FEA), boundary element analysis (BEA) can be used for any type of structures in 3-D configuration taking into account many complicated details such as large deformation, material non-linearity, change in geometry and time integration effect. In this paper different numerical modeling methods of fretting wear are reviewed. FEA MODELINGWith the rapid development of high performance computers and the methods for solving non-linear problems, FEA have applied to simulate the process of fretting wear. Simulation of wear involves solution of a general contact problem, which is highly non-linear due to the contact boundary conditions between the interfaces [3].In the last ten years literature, there are two main methods to simulate the process of fretting wear according ...

ResumenLa simulación del desgaste mediante el Método de Elementos Finitos (MEF) es una técnica que presenta grandes ventajas para la mejora del diseño de componentes ya que permite reducir el coste que conlleva la experimentación (tiempo de ensayo, materiales, medidas tribológicas). En el caso concreto de la optimización de sistemas multihilo sometidos a fretting, como es el caso de los cables metálicos donde se dan contactos cilindro-cilindro, este método puede resultar especialmente eficiente. Sin embargo, la simulación del desgaste resulta una técnica compleja ya que consta de dos núcleos importantes: por un lado, la resolución del contacto y, por otro, la introducción del modelo de desgaste, requiriendo, para ello, de un coste computacional muy importante. Por ello, en este trabajo se define una metodología a seguir con el fin de optimizar el modelo, en términos de tiempo computacional, para un sistema bloque-cilindro. La metodología definida sería aplicable a todos los modelos de desgaste, de geometrías más complejas. Finalmente, se introduce una técnica que consiste en la introducción de un acelerador de desgaste variable y autoajustable, teniendo en cuenta la evolución de la presión máxima de desgaste y el incremento umbral de desgaste. Esta técnica resulta indispensable en cuerpos sometidos a grandes desgastes, reduciendo el tiempo computacional en un 87 % y un error inferior al 1 %.

Optimized methodology for the wear simulation of metallic materials AbstractThe wear simulation with finite element method (FEM) presents great advantages for the improvement of components, because of the reduction in the cost in comparison to the experimental procedure (test time, materials, tribological measurements). In the case of wire rope optimization, where one of the great problems is wear due to fretting in cylinder-cylinder contact points, this method could be efficient. Nevertheless, the wear simulation results in a complex methodology: on the one hand is needed to solve the contact problem and on the other hand the introduction of the wear model. For this reason, this methodology results in high computational time consuming. Consequently an efficient methodology for the optimization of the model, in terms of the reduction of computational time, is presented in this work for a block-on-ring system. Finally a variable wear speed factor and auto-fitting with respect to the evolution of maximum contact pressure and with respect to the maximum limit wear increment is introduced. This is necessary, in systems where high amount of wear is presented with a reduction of 87 % in computational time and an error of less than 1 %.
