Abstract
Recent developments in numerical and experimental techniques for the analysis of deformation mechanics in metal forming processes are presented. New developments of slip-line nets and the introduction of matrix operators in the construction of slip-line fields are reviewed. The application of the finite-element method, the visioplasticity method, and the finite-difference method for the analysis of metal forming processes are described. Detailed results are presented in terms of deformation patterns, and velocity, strain and stress distributions. The wealth of information obtainable using the visioplasticity method is demonstrated. Especially noteworthy are the prediction of central burst formation, grain distortion, and die design.
