“…The intervertebral discs (Fig. 1) were prepared by cutting posterior elements and muscular and ligamentous structures from them [4,15,17]. The inferior semivertebral body was embedded in polyurethane resin.…”

“…To achieve these models, it is necessary to know the mechanical properties of the different structures of the human body, and we have focused first on the intervertebral disc. Most studies of the dynamic behaviour of the intervertebral disc have focused on the physiological loading of daily life and have considered creep [13], cyclic loading [2, 6,14,15,16,17], fatigue with a frequency around 1 Hz [1,19] or impact tests [22]. The goal of this study is to characterise the dynamic stiffness and damping of human intervertebral discs subjected to vibration from 5 to 30 Hz in a sitting position in a car.…”

“…However, viscoelastic models [67,75] have limited capabilities in describing the known viscous effects associated with the interstitial fluid flow. Previous studies have shown [17] that interstitial fluid pressurization plays an important role in the load support mechanics of articular cartilage.…”

In this chapter, an asymptotic modeling methodology for tibio-femoral contact is developed, based on the asymptotic models of frictionless unilateral contact interaction between thin cartilage layers. In Sect. 7.1, the normal contact forces, which are needed for multibody dynamics simulations, are determined analytically based on the exact solution for elliptical contact between thin cartilage layers generally modeled as viscoelastic incompressible layers. In Sect. 7.2, the equivalent HuntCrossley model for articular contact is developed in the framework of the short-time contact model for thin bonded biphasic layers.

In Sect. 5.1, we develop a linear biphasic theory for the case of a transversely isotropic elastic solid matrix with transverse isotropy of permeability. In Sects. 5.2 and 5.3, we consider the linear biphasic models of confined and unconfined compression, respectively, for the biphasic stress relaxation and the biphasic creep tests. Finally, in Sect. 5.4 we outline the biphasic poroviscoelastic model, which accounts for the inherent viscoelasticity of the solid matrix.
