Predictive modelling of the mechanical properties and failure processes in hydroxyapatite- polyethylene (Hapex) composite.

The development of a wide range of hydroxyapatite polyethylene composites for medical applications is increasing the need for accurate predictive modelling. The objective of this work was to elucidate the observed mechanical processes and failure processes in this material using the finite element analysis method. The need for full three-dimensional modelling of this material has been shown. The results from this predictive model lead to accurate predictions of measured mechanical properties, and allow deduction of possible routes to improved ductility at high volume fractions.

Predictive modelling of hydroxyapatite-polyethylene composite.

A predictive model for hydroxyapatite-reinforced polyethylene composite has been developed using the finite element analysis method. The simulation is based on the analysis of a representative cell. Results for the complete material can be derived using a spatial statistical material model. Predicted values of Young's modulus are found to be in reasonable agreement with experimentally measured values over a wide range of hydroxyapatite volume fraction. The predictive model can be used to investigate the micromechanical behaviour of the material. This investigation leads to significant elucidation of the failure processes for this material.
