DOI: 10.1016/j.ijplas.2019.06.013
Abstract: Abstract In elastic and plastic deformation of glassy polymers and with the increase of deformation, the material would exhibit elastic, viscoelastic, and viscoelastic-viscoplastic (VE-VP) responses in sequence. These deformation behaviors should be constitutively modeled in… read more here.
