Abstract

Stress concentrators of different scales inherent in polycrystals tend to form mesosubstructures under load. Television-optical images of displacements are obtained for the Ni-Ti alloy to study the deformation and fracture behavior. Discussed are similarity laws in connection with the formation of dissipative structures at the micro- and macro-scale level.
