About Book

Showcasing vital engineering applications to transient and dynamic pertubations of macromolecular materials, structural recovery’s role in mechanical responses in the glassy state, and viscoelastic parameters that condition the non-Newtonian behaviour of polymers, this work presents a systematic account of the responses of macromolecular materials to mechanical force fields. It focuses on the most important features of the linear stress-strain relationships for ideal solids and liquids. Structure of polymers; crystalline and amorphous states in polymers; rubber elasticity; stress-strain relations for ideal solids and ideal liquids; linear viscoelasticity – viscoelastic functions; dynamic viscoelastic functions; experimental determination of viscoelastic properties; viscoelastic behaviour of polymers above the glass-transition; retardation and relaxation spectra; viscoelastic models; molecular models of the viscoelastic polymers; viscoelasticity of glassy and semicrystalline polymers; flow behaviour of polymer melts and solutions; yield crazing and fracture; reinforced polymers; multiaxial analysis of linear viscoelastic stress; flexion and torsion of viscoelastic rods.
