Abstract
Finite element analysis (FEA) have been widely and effectively used to predict the behavior of a part or assembly prior to manufacturing process. Several software is good for computerizing the FEA process. However, based on FEA running in types of software, the difference comes in huge number. Until today, there is no one literature discussing which software that close to the real number on physical tests. The accuracy of prior computational prediction, particularly in medical devices manufactures including bone-plate, is highly needed to minimize mistakes and reduce expenditure. This paper aims to verify the most accurate one from the finite element analysis that has been run in four software. Researcher conducted two methods of using mathematical approach and the hardness Rockwell C test. A three-dimensional (3D) model, allocates for bone-plate implant, was made and printed using Ti6Al4V. FEA of a bone plate cut performed in COMSOL, Ansys, Abaqus, and Inventor using a precise constrained and load number of 1471 N. The average von Mises stress (VMS) for each software is 1.625e-03 GPa for COMSOL, 1.98865e-01 GPa for ANSYS, 1.0895e-6 GPa for Abaqus, and 2.071e-02 GPa for Inventor. The hardness Rockwell C test shows in five iterations using 150 Kgf and produces 1.595 GPa. Among all software, in this experiment, Ansys presents as the closest result compared to manual calculations and the hardness Rockwell C test. Besides giving an authentic FEA software option, a claim that Ansys can produce the truest number need further confirmation using different models and methods.
