Biphasic model of cartilage
WebJan 1, 2014 · The conewise model was later combined with the biphasic poroviscoelastic model in order to capture load responses of unconfined compression and uniaxial tension simultaneously (Huang et al., 2001). The triphasic and biphasic models predict almost the same equilibrium responses (Ateshian et al., 2004). The reason for that is the … WebConstitutive Model. We described cartilage as a biphasic continuum î= îS+ î of a porous solid phase îS saturated with a fluid phase îF. We calculated the total Cauchy stress as [7,8] Ë=− L ÷+2 éS ô S !ΨS ! S ôS T=− L ÷+ Ë E S, (1) where L is the fluid pressure, ÷ is the identity, éS is the partial density

WebFeb 1, 1980 · We also concluded that 1) a nonlinearly permeable biphasic model, where the permeability function is given by an experimentally determined empirical law: k = A(p) exp [α(p)e], can be used to describe more accurately the rheological properties of articular cartilage, and 2) the frictional drag of relative motion is the most important factor ...
WebNov 25, 2011 · The biphasic model is the most traditional model of articular cartilage and other fluid-saturated tissue which takes the interstitial fluid movement into account (Mow et al., 1980). In the biphasic theory, the solid matrix and fluid are assumed to be intrinsically incompressible and nondissipative.
