摘要：

Meso-scale frictional dynamics of elastic-plastic bodies were studied using Smoothed Particle Hydrodynamics (SPH) method. Our coarse-grained model can consider the plasticity, wear and heating based on the continuum dynamics and molecular approach. The former mainly expresses the elastic-plastic properties and the latter plays the interaction between friction surfaces. In the system that two bodies with rough surfaces were set face to face, a series of the friction, wear were qualitatively reproduced. This model will be in future effective to clear the tribological mechanism, such as friction reduction and low seizure, with varying the conditions.
