Abstract

Metallurgical effects on shear band behavior were studied by applying a state of uniform dynamic shear strain and then suddenly removing it by explosively expanding a hollow specimen cylinder to a diameter determined by a massive confining cylinder. Because geometry-induced stress concentrations are absent and because shear band development can be stopped at various stages, the procedure emphasizes the role of metallurgical features on shear band activity.
