..., we suggest a Poisson's ratio of 0.125 to be used in biphasic models of the intervertebral disk. Poisson's ratio intervertebral disk nucleus pulposus poroelastic viscoelastic The nucleus pulposus is the hydrated central region of the intervertebral disk (IVD) and is composed...

... analysis chondron poroelastic collagen proteoglycan finite element method Articular cartilage is the primary load-bearing soft tissue in diarthrodial joints and exhibits apparent viscoelastic responses including creep, stress relaxation, and hysteresis under cyclic loading. The cartilage...

... of constriction flow in a poroelastic solid is presented. A finite element model was developed and validated against this physical model. The finite element model showed that decrease of the constriction hole area not only increases the resistance to fluid flow, but also causes the direction-dependency of flow...
