Definition of terms relating to the non-ultimate mechanical properties of polymers : (IUPAC recomendations 1998)

Abstract

The document gives defínitions of terms related to the non-ultimate mechanical behaviour of polyrneric rnaterials, in particular bulk polymers and concentrated solutions and their elastic and viscoelastic properties. The terms which have been selected are those met in the conventional mechanical characterization of isotropic polyrnenc materials. They have additionally been lirnited to those which can be defúied precisely and with mathematical rigour. They are arranged in sections deaiing with basic defínitions of stress and strain, deformations used experirnentally, stresses observed experimentally, quantities relating stress and deformation, linear viscoelastic behaviour, and oscillatory deformations and stresses used experimentally for solids. An index, an alphabetical list of terms and a glossary of symbols are included for ease of reference.
