Abstract

Observations are reported in relaxation tests under tension and retraction on polypropylene/clay nanocomposites with various contents of filler. A two-phase constitutive model is developed in cyclic viscoelasticity and viscoplasticity of nanocomposites. Adjustable parameters in the stress-strain relations are found by fitting the observations. Ability of the constitutive equations to describe characteristic features of the time-dependent behavior of nanocomposites under cyclic deformation is confirmed by numerical simulation.
