10 Deformation instabilities in extensional plastic flow of polymers

10.1 Overview

Complementary to shear localization, which was considered prominently in the mechanistic discussions of plastic shear of atomic glasses and glassy polymers in Chapters 7 and 8, are flow instabilities in extensional plastic flow of materials, for which the destabilizing area reduction is counteracted by strain hardening and the strain-rate dependence of plastic resistance. Such responses limit the range of deformation processing of metals and polymers in extensional deformation and are also of fundamental interest for many problems involving fracture. In this chapter we consider the ranges of stable extensional plastic flow governed by forms of strain hardening ...
