Bulk deformation during linear extension of certain solid polymers

This article describes an experimental study of the bulk deformation in a forward-and-reverse creep cycle of low-density polyethylene and plasticized acetyl celluloses under stresses beyond the linearity region of the viscoelastic properties.All-Union Scientific-Research Institute of Synthetic Resins, Vladimir.
