The effect of a longitudinal stretch and a pressure-induced inhomogeneous radial deformation on the scattering of antiplane elastic waves from a cylindrical cavity is determined. Three popular nonlinear strain energy functions are considered: the neo-Hookean, the Mooney-Rivlin and a two-term Arruda-Boyce model. A new method is developed to analyse and solve the governing wave equations. It expl...

The purpose of this study was to create a polymer phantom mimicking the mechanical properties of soft tissues using experimental tests and rheological models. Multifrequency Magnetic Resonance Elastography (MMRE) tests were performed on the present phantom with a pneumatic driver to characterize the viscoelastic (μ, η) properties using Voigt, Maxwell, Zener and Springpot models. To optimize the...

The steady flow of a Reiner-Rivlin fluid with Joule heating and viscous dissipation is studied. We present a novel technique for accelerating the convergence of the spectral-homotopy analysis method. Solutions of the nonlinear momentum and energy equations are obtained using the improved spectral homotopy analysis method. Solutions were also generated using the spectral-homotopy analysis method...

A layer of compressible, rotating, elastico-viscous fluid of related density heated & soluted from below is considered in the presence of vertical magnetic field to include the effect of Hall currents. Dispersion relation governing the effect of visco-elasticity, salinity gradient, rotation, magnetic field and Hall currents is derived. For the case of stationary convection, the Rivlin-Erickson ...

Abstract Atherosclerosis is one of the most common cardiovascular diseases leading to high morbidity. The study arterial dynamics using fluid–structure interaction (FSI) technique by taking into account physiology flow, critical hemodynamic parameters can be determined which plays a crucial role in predictive medicine. Due advances computational facilities, coupled field analysis such as FSI fa...
