Biphasic model of cartilage
WebApr 21, 2009 · In particular, this model can predict the transition of Poisson’s ratio from very low values in compression (∼ 0.02) to very high values in tension (∼ 2.0) . Most of these phenomena cannot be explained when using only three orthogonal fiber bundles to describe the tissue matrix, a common modeling assumption used to date. http://web.mit.edu/cortiz/www/3.052/3.052CourseReader/27_BiomechanicsofCartilage.pdf
Biphasic model of cartilage
Did you know?
Webvations suggest that cartilage behaves like a sponge, albeit one that does not allow fluid to flow through it easily. Recognizing that fluid flow and deformation are interde-pendent has led to the modeling of cartilage as a mixture of fluid and solid components [59–61]. This is referred to as the biphasic model of cartilage. In this modeling ... WebBiphasic Theory is a mechanical model developed by Van C. Mow and coworkers for soft tissue, especially articular cartilage, based on Poromechanics. The mechanical behavior of many soft tissues can be best understood by considering it as a multiphasic material. In biphasic theory, the two principle phases are the solid matrix phase and the movable …
