文摘

Plastic flow instability in ductile plates subjected to dynamic biaxial loading. The role of geometrical defects and loading path is analysed. The localization pattern is characterized with finite element simulations. Numerical results are compared against predictions of a linear stability analysis. The effect of the loading path and inertia on the necking pattern is brought to light.
