RISA Bimodular Polyconvex Anisotropic Strain Energy Function for Articular Cartilage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A strain energy function for finite deformations is developed that has the capability to describe the nonlinear, anisotropic, and asymmetric mechanical response that is typical of articular ...
Simulating the Growth of Articular Cartilage Explants in a Permeation Bioreactor to Aid in Experimental Protocol Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recently a cartilage growth finite element model (CGFEM) was developed to solve nonhomogeneous and time-dependent growth boundary-value problems (, 2008, “A Nonlinear Finite Element Model of ...
A Special Theory of Biphasic Mixtures and Experimental Results for Human Annulus Fibrosus Tested in Confined Compression
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A finite deformation mixture theory is used to quantify the mechanical properties of the annulus fibrosus using experimental data obtained from a confined compression protocol. Certain constitutive ...
A Growth Mixture Theory for Cartilage With Application to Growth-Related Experiments on Cartilage Explants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present a growth mixture model for cartilage. The main features of this model are illustrated in a simple equilibrium boundary-value problem that is chosen to illustrate how ...
A Nonlinear Constituent Based Viscoelastic Model for Articular Cartilage and Analysis of Tissue Remodeling Due to Altered Glycosaminoglycan-Collagen Interactions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A constituent based nonlinear viscoelastic (VE) model was modified from a previous study (, , 2006, “ A Constituent-Based Model for the Nonlinear Viscoelastic Behavior of Ligaments,” J. Biomech. ...
A Cartilage Growth Mixture Model With Collagen Remodeling: Validation Protocols
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A cartilage growth mixture (CGM) model is proposed to address limitations of a model used in a previous study. New stress constitutive equations for the solid matrix are derived and collagen ...
In vitro Articular Cartilage Growth with Sequential Application of IGF-1 and TGF-β1 Enhances Volumetric Growth and Maintains Compressive Properties
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In vitro cultures with insulin-like growth factor-1 (IGF-1) and transforming growth factor-β1 (TGF-β1) have previously been shown to differentially modulate the growth of immature bovine articular ...
