A basic study on the prediction of local material behavior of composite bone plate for metaphyseal femur fractures

Abstract

This paper presents a method for estimating the local property changes and predicting the failure of composite materials experiencing large shear deformations during the draping process. This method was applied to the bone plate used for metaphyseal femur fractures because it has a complex geometry. The local property changes of fabric composites due to macro/microscopic deformations during the draping process were evaluated by various tests, and the results were used to predict the static/fatigue behaviors of the bone plate. This paper is expected to present useful information on the design of composite structures with complex geometries and their performance evaluation.
