Abstract

This paper examines bone fatigue damage using Finite Element Analysis (FEA) to predict changes in modulus, damage and cycles to failure.The MATLAB-coded material model has been previously implemented in a full FEA package.It is based on published models of damage verified with experimental data.The MATLAB program inputs a finite element mesh and simulates the damage iteratively.Four meshes are examined:a machined tensile specimen of the bone, a machined bending specimen, a single strut of cancellous bone, and a 2-D slice of cancellous bone.This model is a fast testing method for ideas, allows easy comparison of different test geometries and material damage models, and may help to bring the study of bone damage to a broader audience.
