速度・状態依存性摩擦モデルを用いたスティックスリップ運動開始時の数値解析

抄録

The description of stick-slip motion on contact surfaces having flexibility is important. However, conventional analysis mainly focuses on steady state of stick-slip motion, and thus the behavior at the onset of stick-slip motion is ignored. In this study, a numerical analysis of onset of stick-slip motion is conducted using rate- and state-dependent friction model, which can rationally describe the reciprocal transition between the static friction and the kinetic friction by a unified formulation.
