摘要: This article discusses the application of visioplasticity method to evaluation large plastic strains such as those occurring in metalforming. Although this can be used for any mode deformation, its plane-strain deformation is treated here. The distortion a quadrilateral element grid tracked compute during deformation. In each case two lines (length before and after direction cosines deformation) determine element. has been verified by basic cases uniaxial compression, tension, pure shear, rotation elements. effect choice upon results strain calculation also discussed.
