  • NRN142 Sheer Thinning of Noncolloidal Suspensions

    American Physical Society

    • Modelling

    In this letter we propose a non-Newtonian model of interparticle lubrication forces to explain shear thinning in noncolloidal suspensions. We show that hidden shear-thinning effects of the suspending medium, which occur at shear rates orders of magnitude larger than the range investigated experimentally, lead to significant shear thinning of the overall suspension at much smaller shear rates.

  • NRN119 - Distortion-resistant and locking-free eight node elements effectively capturing the edge effects of Mindlin-Reissner plates

    Engineering Computations

    • Modelling

    A simple shape-free high-order hybrid displacement function element method is presented for precise bending analyses of Mindlin–Reissner plates. Three distortion-resistant and locking-free eight-node plate elements are proposed by utilizing this method.

  • NRN113 - Three-dimensional all-dielectric metamaterial solid immersion lens for subwavelength imaging at visible frequencies

    Science Advances

    • Materials

    Although all-dielectric metamaterials offer a low-loss alternative to current metal-based metamaterials to manipulate light at the nanoscale and may have important applications, very few have been reported to date owing to the current nanofabrication technologies.

  • NRNF28 - Quantification of in-vivo pre-strains in human aortic valve leaflets

    Science Direct

    • Materials

    Herein we present a completely non-invasive approach for determining heterogeneous strains – both functional and residual – in semilunar valves and apply it to normal human AV leaflets. Transesophageal 3D echocardiographic (3DE) images of the AV were acquired from open-heart transplant patients, with each AV leaflet excised after heart explant and then imaged in a flattened configuration ex-vivo.
