Abstract

Localized necking is simulated by using three-dimensional elasto-plastic bifurcation analyses. In this study, localized deformations just before the shear fracture of specimens with various width-thickness ratios are analyzed using the J₂-flow hardening theory only. After detecting a bifurcation point precisely and conducting a branch-switching procedure, excellent correlation is demonstrated between the numerical and the experimental results.
