Abstract: Both 3-D hexahedral and 2-D axisymmetric cylindrical finite element cell models have been applied for studying the mechanical properties of hydroxyapatite particle (HAp) reinforced Poly-1-lactide acid (PLLA) polymer. The primary objective of this paper was to study the characteristics of the two models. After a cell was separated into finite elements and proper boundary conditions were applied, the distributions of the direct and von Mises stresses were computed. The potential mode of failure of the composite was forecasted on the basis of the stress distributions. Furthermore, the values of overall Young's modulus and Poisson's ratio were predicted. The Halpin-Tsai semi-empirical formula was also employed for comparison, and the experimental data from other researchers have been adopted for verification of the results predicted from our model. In accordance with the numerical simulation, some conclusions were drawn for using the two cell models.
