Paper Title:
Research on the Deformation Area Materials’ Stress and Contour Surface’s Forming Mechanism of Closed Extruding Fine-Blanking
  Abstract

It analyzed the influence on parts’ shear surface quality by the stress and strain in the deformation area of materials. The analysis shows that the continuum linear rigid-plastic model and the fracture failure criterion in the light of damage factor, which is based on the microcosmic structure, and can accurately simulate the closed extruding fine-blanking processing; and that the higher the filling rate of outer ring is, the larger pressure stress are the deformation materials under; also that the greater the compressive stress of deformation area materials is, the higher does the deformation limit, the time of materials’ crack is delayed.
