INFLUENCE OF GEOMETRY AND DESIGN PARAMETERS ON FLEXURAL BEHAVIOR OF DYNAMIC COMPRESSION PLATES (DCP): EXPERIMENT AND FINITE ELEMENT ANALYSIS

Abstract

This work aimed to study the effect of various geometric parameters on bending behavior in orthopedic dynamic compression plates (DCPs) in order to achieve suitable criteria in an optimum design of these plates. Modeling, simulation, and analysis were performed through the finite element software of ABAQUS. In order to verify the model, four-point bending tests on several actual plates were conducted. In addition, the classical beam theory was applied for the theoretical estimation of the maximum tensile stress in the outer fiber and the longitudinal stresses of plates. Finite element analysis (FEA) results indicated relatively good conformity with the empirical results and those of beam theory. Based on the results, the distance of the holes from the plate edge was observed to be the most effective parameters on flexural behavior. It was also found that the flexural properties are maximized at a unique distance between the outside edge of the hole and the edge of the plate.
