A nonlinear biphasic viscohyperelastic model for articular cartilage.
TLDR
A nonlinear biphasic viscohyperelastic model that combines the intrinsic viscous effects of the proteoglycan matrix with a nonlinear hyperelastic constitutive equation is proposed and shows an excellent fitting of finite-deformation confined compression stress relaxation data.About:

Hyperelastic Energy Densities for Soft Biological Tissues: A Review
TL;DR: A review of these constitutive equations can be found in this article, where the authors propose a review of the literature on constitutive models for soft tissues. But they do not consider the model that describes the behavior of the material.

Importance of Collagen Orientation and Depth-Dependent Fixed Charge Densities of Cartilage on Mechanical Behavior of Chondrocytes
TL;DR: The current model highlights that the collagen orientation and the depth-dependent negative fixed charge densities of articular cartilage have a great effect in modulating the mechanical environment in the vicinity of chondrocytes, and it provides an important improvement over earlier models in describing the possible pathways from loading of artic cartilage to the mechanical and biological responses of chonds.
Journal ArticleDOI
Validation and application of an intervertebral disc finite element model utilizing independently constructed tissue-level constitutive formulations that are nonlinear, anisotropic, and time-dependent
TL;DR: A newinite element model of the intervertebral disc was developed to validate the model's nonlinear and time-dependent responses without tuning or calibration, and to evaluate the effect of changes in nucleus pulposus, cartilaginous endplate, and annulus fibrosus material properties on the disc mechanical response.
Journal ArticleDOI
Biaxial tension of fibrous tissue: using finite element methods to address experimental challenges arising from boundary conditions and anisotropy.
TL;DR: Finite element simulations were used to quantify load transmission from the clamps to the ROI in biaxial tension and to formulate a correction factor that can be used to determine ROI stresses, which may lead to more accurate representation of the mechanical response of fibrous soft tissue.

Meniscectomy alters the dynamic deformational behavior and cumulative strain of tibial articular cartilage in knee joints subjected to cyclic loads
Yongnam Song,Yongnam Song,Joan M. Greve,Dennis R. Carter,Dennis R. Carter,Nicholas J. Giori,Nicholas J. Giori +6 more
TL;DR: Tibial articular cartilage in the central load bearing region remains chronically deformed and dehydrated, even after cessation of loading, consistent with the central fibrillation and peripheral osteophyte formation seen in post-meniscectomy osteoarthritis.
