New principles are introduced for the formulation of dynamic problems in viscoelasticity for the most general case of anisotropy. One is a variational principle derived from irreversible thermodynamics. The other a correspondence principle between viscoelasticity and elasticity. Applications to the mmics of viscoelastic plates and rods are developed as examples. The variational principles are a...

Janus-faced viscoelastic gelling agents—possessing both elastic and viscous characteristics—provide materials with unique features including strengthening ability under stress a liquid-like character lower viscosities relaxed conditions. The mentioned multifunctional is manifested in several body fluids such as human tears, synovial liquids, skin tissues mucins, endowing the special physical re...

Rheological characterization of complex fluids subjected to cyclic shear-rate sweep often exhibits hysteresis. Since both viscoelastic and thixotropic materials show hysteresis loops, it is important understand distinguishing features (if any) in the same shown by either. Lately, there has been substantial work that attempts relate area enclosed loop with manner which shear rate varied cycle, o...

A self-contained review is given for the development and current state of implicit constitutive modelling viscoelastic response materials in context strain-limiting theory.
