Abstract

The article deals with the mathematical simulation of biological tissues, the methodology and realization of experimental measurement of human hyaline cartilage is documented and carried out in vitro. The material characteristics of cartilage are presented on the basis of statistical analysis. The transversal isotropic material was chosen for its mathematical characterization and the constants Ei, Gij, ┬Áij (i, j = 1, 2, 3) were determined in compliance matrix Sij. These results were used for the FEM submodel of cartilage and that was subsequently integrated into the entire model of the human hip joint.
