Abstract

Modeling the geometry and behavior of human bones is of the most concern when dealing with bone remodelling (external and internal) and poroelastic analysis. Complex geometries are frequently found in the human skeleton as well as orthotropic behavior of bone tissue. Spongy bone has a completely different constitution as compared with compact bone, which adds another relevant consideration if we want to get reliable results in biomechanical analysis. The modeling of both compact and spongy human-bone tissue is carried out by using packaging-particle methods. The methods generate circles (2D domains) and spheres (3D domains) in a random manner for the representation of non homogeneous and porous media. These methods were optimized with front-advance algorithms, which lead to a significant reduction of the very large set of circles and spheres. The methods use non-spherical particles (ellipsoids) to represent spongy bone. Some preliminary models of human bones are discussed.
