速度・状態依存性摩擦挙動のマルチスケール解析: メソ―マクロスケール非連成解析

抄録

In recent years, studies on frictional sliding behavior at the nano-scale and meso-scale have been widely conducted. However, there are few studies that consider for multi-scale. Therefore, in this study, we propose the multi-scale analysis method of rate- and state-dependent friction. As a macro-model, the rate- and state-dependent friction model based on elastoplastic theory is adopted, while he multi-point contact model consisting of a large number of spring-mass systems is adopted as a meso-scale model. We show that the microscopic elementary process in the finite element analysis introducing the macro model can be examine the meso-scale behavior of rough surfaces.
