Abstract
In the present study, laminated composites of polymethyl methacrylate (PMMA)—titanium (Ti) with different ply orientation were designed and three different crack angles (20°, 40° and 50°) were considered in femur bone to investigate the effect of crack angle on the stress distribution in the bone. PMMA was selected as matrix and titanium was selected as fiber from 0.2 to 0.5 volume fraction (Vf). 3D model of bone implant assembly was designed by using computer-aided drafting (CAD) and simulation was carried out with the help of ANSYS Workbench® software. Laminated composites with different ply orientations with different volume fractions of fiber were analyzed, and optimum combination was abstracted with an objective to attain higher and uniform stress distribution throughout the bone. From the results, it is observed that the crack angle effects the stress distribution in the bone even though the same laminated composite is used as implant.
