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 timedependent
behavior of nanocomposites under cyclic
deformation is confirmed by numerical simulation. POLYM.
