A study has been conduct to verify the compatibility of the biomaterials which is Polymethylmethacrylate (PMMA) by developing a frontal human head impact test using finite element analysis (FEA). This study is to compare the results between simulation and experimental result conducted by previous study. To conduct this study, the process involve is to develop finite element model of spherical skull in SOLIDWORKS and to analyze the data analysis using ANSYS Workbench. It is to study the impact conditions of human skull during a human head impact on the resulting of total deformation. Three finite element model of spherical skull are created using SOLIDWORKS, which the three of them is distinguished by their thickness which resembles the thickness of real frontal human skull. Then, all of the models are exported to the software called ANSYS Workbench to create a simulation of a frontal human head impact test. The result of the simulation is total deformation is then analyze by calculating the percentage error and percentage difference between the simulation result and the experimental result by previous study. The average percentage error between the simulations of spherical skull models with previous experimental result is 12.79%, while the lowest percentage error is around 10.91%. The average percentage difference for the simulation result using PMMA with the previous experimental result is around 4.74%, and the lowest percentage difference is around 3.00%. In conclusion, the result shows the PMMA is suitable as bone substitution for frontal human skull. © 2006-2016 Asian Research Publishing Network (ARPN). All rights reserved.
