Abstract
The forward flow generated near the contact surface in the rolling disks in high
loading is numerically approached to study from the points of view of the
kinematics and the mechanics by using FE analysis. Beginning with the
fundamental study on the behavior of the contact surface of the disk, the
influence of the deviation of the center position of the disk on the plastic flow is
researched. That is, the behavior of the material near the contact surface is
analyzed and the elastic-plastic deformation in the disk is studied by using 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 it may be generated a little in
