Experimental data from uniaxial tensile tests on smooth and notched specimens of aluminium alloy 5083-H116 show that the material exhibits negative strain-rate sensitivity for strain rates within a certain range. The negative strain-rate dependence; which is attributed to dynamic strain aging; leads to serrated stress-strain curves; discontinuous plastic flow and propagating deformation bands during plastic straining (also denoted as the Portevin-Le Chatelier effect). Band analysis and linear perturbation analysis are performed using simple elastic-viscoplastic constitutive equations that include negative strain-rate sensitivity in a simplified manner. The negative strain-rate sensitivity allows for jumps in the plastic strain rate; which in turn permits the existence of localisation bands for the elastic-viscoplastic model. The simple elastic-viscoplastic constitutive model has been implemented in LS-DYNA; and non-linear finite element simulations of smooth and notched tensile test specimens are performed; allowing more detailed investigations into the effects of the negative strain-rate sensitivity on the material's behaviour. © 2005 Elsevier SAS.
