A continuum approach based on qualitative micro-structural physics and
thermodynamic arguments has been elaborated for modeling of such interactive
phenomena as yelding, thixotropy, nonlinear viscoelasticity, frozen memory,
and stress localization. This type of modeling has been successfully applied
to various media, such as coagulating suspension, highly filled polymers,
concentrated solutions of surfactants, and elasto-viscoplasticity in metals.
The mutual feature in the above systems is the presence at rest of a
specific "structure" which can be destroyed at higher stresses and restored
again after any type of unloading. Examples of this type modeling are
presented in this lecture and compared with experimental data.
