The present article provides a perspective for computational predictions relating to flow localization under a wide range of deformation rates for a variety of materials characterized by constitutive equations incorporating the strain-rate and temperature sensitivities, and strain-rate-history, temperature-history, and strain-gradient dependences of the flow stress. The regularization schemes to remedy the problems associated with spurious mesh sensitivity and incorrect convergence in finite-element prediction of flow localization behavior are reviewed. Various aspects of flow localization behavior of plane strain blocks with different shapes and sizes under a wide range of tension rate are discussed on the basis of computational simulations.
