Abstract

A new orthotropic strain energy function is proposed for describing the observed tension-compression non-linearity of the solid matrix of articular cartilage. This proposed function is based in the exponential form used by Cohen [6] and uses an approach similar to that of Quapp and Weiss [15] to incorporate the tension-compression non-linearity of the tissue. Under infinitesimal strains it can reduce to the Conewise Linear Elastic (CLE) model of Cumier et al. [7], or it can allow for a smooth transition between tension and compression.
