Abstract
Presented in this paper is the simulation of intermittent yielding phenomena experimentally observed in aluminum and copper alloys. An earlier developed macro-meso yield criterion is modified to take into consideration multiple shear band propagation. Calculations of tension of an Al6061 alloy test piece as an example were performed to investigate the serrated character of the stress-strain curve. The dynamics of stress and strain patterns on the macro and mesoscale levels is studied in details.
