Deformation Bands in Amorphous Polystyrene and their Relation to the Slip Line Field

Abstract

POLYSTYRENE deformed in plane strain compression shows inhomogeneous plastic shear deformation in the form of intense shear deformation bands1. These bands are distinct from craze marks and must not be confused with the latter. Crazes occur in a direction perpendicular to the principal tensile stress, while the deformation bands are nearly parallel to the planes of maximum shear stress2,3.
