Modeling of Viscoelastic Shear: A Nonlinear Stick-Slip Formulation

Abstract

We present a class of nonlinear dynamic viscoeleastic models for materials subjected to shear stress. The model equations are based on a continuum variation of a reputation model in which chemically cross-linked (CC) systems of molecules act as constraint boxes per unit volume for physically constrained (PC) systems of molecules. Results from validating the model with dynamic shear experiments are given and a stability analysis for the corresponding linearized systems is discussed.
