Abstract
This work is focused on the analysis of Lueders bands and Portevin Le-Chatelier (PLC) effect using experimental and computational data. The Lueders bands are related to the initiation of localization bands and movement of fronts of the underlying plastic zones. The PLC effect is associated with Dynamic Strain Aging and caused by interactions between solute atoms and mobile dislocations during plastic processes. Tensile tests of aluminum alloy AW5083 specimens have been conducted for three strain rates at room temperature. Both Lueders and PLC bands are reflected by the obtained force-displacement diagrams. Displacement and temperature fields are recorded during the experiments. A large strain thermo-viscoplasticity model with the Estrin-McCormick model, enhanced by switch functions, is applied in simulations, whereby good agreement between experimental data and computed results is obtained.
