| contents | In this paper, we present a comprehensive analysis of the contact mechanics associated with a micron-sized sliding asperity, which plays a crucial role in the abrasive wear processes. Utilising nanoscratch testing, we experimentally investigate the deformation and employ High-Resolution Electron Backscatter Diffraction (HR-EBSD) to characterise the resulting strain fields at various locations in the residual nanoscratch. To simulate these experiments, we utilise a physically-based Crystal Plasticity Finite Element (CPFE) model, enabling a three-dimensional simulation that can accurately capture the measured elastic and plastic strain fields around the sliding contact. This knowledge serves as a foundation from which we may be able to discern the multi-physical processes governing micro-scale wear phenomena. |
