RESEARCH ON MECHANISM OF INTERIOR-HOLLOW DEFECT DURING THE DEFORMATION OF CROSS WEDGE ROLLING

Abstract

Abstract: The deformation of the workpiece during cross wedge rolling (CWR) is simulated by using three-dimension finite element soft named deform-3D. The whole information of the workpiece stress and strain field and the material flow discipline are obtained. So the evolvement history of the interior stress and strain state are grasped, and the mechanism of the interior-hollow defect during CWR is explained definitely.

Key words: 3D finite numerical simulation, Cross wedge rolling, Interior- hollow defect, Stress and strain state, Ankle rehabilitation, Muscle activity, Nutation motion, Trajectory planning
