Abstract
With the help of the optical-television measuring system TOMSC the influence of artificial stress macroconcentrators in the form of notches on the strain localization in alloys with clearly pronounced Portevin-Le Chatelier effect was investigated in Al+10%Al2O3 polycrystals under tensile loading. In the case of a few number of notches (from 1 to 3) the strain localization is concentrated in small volumes of the specimen. Large number of notches (from 3 to 42) creates a set of stress concentrators in the working volume of the specimen. The increase of the number of notches leads to an increase of the stress flow and plasticity of the specimen.
