The adiabatic shear banding and its consequences are considered here as deterioration mechanisms incorporated in the dynamic plasticity modelling for high-strength metallic materials following earlier contributions of the present authors. A three-dimensional finite deformation model, starting from a specific scale postulate and devoted to cover a wide range of dissipative phenomena including adiabatic shear banding-related material instabilities, is further developed here. The developments concerned are based on recent experimental evidence and include explicitly post-localization void-sheet formation and growth in the wake of a band cluster. The model enlarged in this way allows for a more detailed description of a late pre-failure stage of shear-dominated deformation. Some model calibration and numerical implementation items are discussed.
