Research Abstract |
The aim of this study is to propose a numerical approach for analyzing stick-slip motion; the approach is based on the finite element method implemented using arate-dependent friction model. First, we propose the rate-dependent friction model based on the elastoplastic formulation. We then demonstrate the capability of the rate-dependent friction model by comparing its results with experimental results obtained under various material and dynamicconditions. Then, a finite element analysis of rate-dependent frictional sliding behavior, includingstick-slip motion, is carried out to examine the effect of the material and geometric properties andboundary conditions on the numerical results. The present numerical approach can consider not only the properties of friction and materials but also variations in boundary conditions.
