On nonlinear viscoelastic deformations: a reappraisal of Fung's quasi-linear viscoelastic model
This paper offers a reappraisal of Fung's model for quasi-linear viscoelasticity. It is shown that a number of negative features exhibited in other works, commonly attributed to the Fung approach, are merely a consequence of the way it has been applied. The approach outlined herein is shown to yield improved behaviour and offers a straightforward scheme for solving a wide range of models. Resul...
متن کاملOn Axisymmetrjc Deformations of Nonlinear Viscoelastic Membranes
In previous work it was shown that a class of axisymmetric viscoelastic membrane problems can be reduced to the numerical solution of a system of partial differential-Volterra integral equations. This general method has the disadvantage that a change in constitutive equation requires rederivation of specific details of the governing system. In this paper, a revised method is presented in which ...
متن کاملA Quasi-linear Viscoelastic Model of Foot-ankle Ligaments
Experimental Procedure. Five fresh-frozen lower-limb cadaver specimens were obtained, and the following bone-ligamentbone specimens were prepared: inferior calcaneonavicular (ICN), long plantar (LP), plantar first-cuneiform first-metatarsal (PFCFM), and posterior tibiotalar (PTT). The LP ligament was not harvested beyond its initial insertion into the cuboid. Ligaments were potted in polymethyl...
متن کاملMultilayer Quasi-Linear Viscoelastic Characterization of Porcine Aorta Using Nanoindentation
In a wide range of applications from traumatic injury to stent grafts, the arterial wall has been considered as a homogeneous single-layer vessel, ignoring the fact that arteries are composed of distinct anatomical layers with different mechanical characteristics. The multilayer nature of arteries has an important influence in the development of mathematical models to predict large deformations...
