✦ Synopsis

If a three-element mechanical model incorporating a stress-dependent thermally activated rate process is used to predict the instantaneous and anelastic components of elastic modulus of high density polyethylene, it is suggested that the measured elastic modulus determines the anelastic response rather than an instantaneous response and, furthermore, it is related to an interlamellar shear rather than a slip process in the crystalline region.
