Abstract
The energy is a crucial factor in dynamical contact analysis. And the complexity of real-world surface morphologies characterized by roughness, poses a considerable challenge for accurately predicting their dynamic contact behaviors. Hence, it is meaningful to explore the influence of surface roughness on energy dissipation. In this study, the two-dimensional geometry with randomly rough surface is reconstructed based on Karhunen–Loève expansion and isogeometric collocation method. And a contact algorithm is tailored for dynamic frictional contact problems by incorporating the Bi-potential method into isogeometric analysis. Numerical results show that roughness factors such as the correlation length and square roughness of the randomly rough surface significantly affect the maximum ratio of real contact area to the normal contact area and the rate of energy dissipation. This work could provide a reference for future research on the dynamic contact between rough surfaces.
