Abstract

Elastic-plastic deformation near the contact surface of the circular disk under high loading T. Sawada & M. Horiike Department of Mechanical Systems Engineering Tokyo University of Agriculture and Technology, Japan Abstract The forward flow generated near the contact surface in the rolling disks in high loading is numerically approached to study from the view points of the kinematics and the mechanics by using FE analysis for the first time. Beginning with the elementary study on the behavior of the contact surface of the disk, the influence of the disk rotation on the plastic flow is examined. The plastic flow in the disk is studied by the plastic deformation law and the stress distributions. Finally, the followings are found: the deviatoric plastic flow cannot be generated in the case that two disks are located just on the centerline, but that it can be generated in the case that the disk centers are deviated normal to the center line OO' by 6 . 1 Introduction
