Wear is defined as "the removal of material volume through some mechanical process between two surfaces." This paper focuses on the steps necessary to evaluate wear due to dry sliding between two surfaces at high velocity. Currently, there is a need to identify and compare materials that can endure sliding wear under severe conditions such as high velocities. The high costs associated with the field experimentation of systems subject to high-speed sliding have prevented the collection of the necessary data required to characterize this phenomenon. Simulating wear through finite elements (FEs) would enable its prediction and would reduce experimentation. In the aerospace, automotive, and weapon industries, such a model can aid in material selection, design, and/or testing of systems subjected to wear.
