Nonlinear Viscoelastic Behavior of Human Cervical Spine Ligaments

Introduction—Spinal ligaments play an important role in spine biomechanics. Accordingly, a precise understanding of ligament mechanical properties is requisite for accurate modeling of the local and global behavior of the spine. Spinal ligaments exhibit nonlinear stressstrain relationships and viscoelastic material behavior. Current literature on the viscoelastic response of cervical spine liga...

Application of nonlinear viscoelastic models to describe ligament behavior.

Recent experiments in rat medial collateral ligament revealed that the rate of stress relaxation is strain dependent and the rate of creep is stress dependent. This nonlinear behavior requires a more general description than the separable quasilinear viscoelasticity theory commonly used in tissue biomechanics. The purpose of this study was to determine whether the nonlinear theory of Schapery o...

Global Existence and Asymptotic Behavior for a Nonlinear Viscoelastic Problem

In this paper the nonlinear viscoelastic wave equation |ut|utt −∆u−∆utt + ∫ t 0 g(t− τ)∆u(τ)dτ − γ∆ut = b|u|p−2u is considered. Using the potential well method a global existence and an exponential decay result are proved. Moreover, for sufficiently large values of the initial data and for a suitable relation between p and the relaxation function g, we establish an unboundedness result.
