Description Finite element (FE) analysis is today one of the most powerful and robust tools used to study and predict the wear behaviour of different mechanical systems. Despite the increasing performance of computers, the huge amount of computational time needed to obtain accurate wear predictions still remains the main limitation of a wider use of FE-based wear predictions. This issue is particularly important for complex three-dimensional models and is mainly due to the iterative process that is required to compute both the evolving contact pressure distribution and the incremental wear depth or volume. Key Objectives Different methods were proposed in the literature in order to reduce the computational cost associated with non-linear FE wear simulations, particularly when many loading cycles are considered. One of the most commonly used approaches is based on the so-called extrapolation technique in which an extrapolation factor is selected to reduce the total number of analyses needed to estimate the final wear amount. The idea behind this method is that one FE analysis is able to represent a number of wear cycles by assuming a steady progression of wear.This work aims at discussing surface wear and investigating the wear sub-modeling technique to a components contact simulation.
