Abstract

A contact simulation with sharp corner by using molecular dynamics method T. Tsuji, N. Noda Department of Mechanical Engineering, Shizuoka University, 3-5, Jyouhoku, Hamamatsu 432, Japan ABSTRACT We investigate contact problems of two rectangular plates by using the molecular dynamics method. The molecular dynamics method is a simulation technique by calculating motion of atoms or molecules. The two rectangular plates are constructed with about 1000 atoms. Each plate is connected each other and applied normal and/or shear deformation. Atom order stress distributions in the neighborhood of the corner are obtained, and the generalized stress intensity factor in atom order is studied. INTRODUCTION A contact problem with a sharp corner is important, because such a corner is a stress singular point and the generalized stress intensity factor can be defined. By this factor, stress field near the corner can be obtained. Thus, this generalized stress intensity factor could be i
