Abstractresearch in the field of biomechanics related to orthopedic implants is rapidly growing in the world, especially for fixation of fractured bone. Fixation is a surgery to locate and attach a plate pressed by screws at the fractured bone. Most of the fracture bones sited in femur. This research focuses on modeling and simulation of plate and screw made of SS316L material for the fixation of the fractured femur using finite element method (FEM). SS316L is a material with good biocompatibility, cheap, and ductile enough. Modeling and simulation done using ANSYS 15.0 software. Simulation results are stress, strain, and total deformation. It is obtained that optimum diameter of screw is 4.5 mm with respect to minimum value of von Mises stress and deformation.Keywordsdeformation, finite element method, screw diameter, SS316L, von Mises stress.

In this paper, finite element analysis for design of plate for fractured femur is presented. The plates with different hole types are simulated. The types of hole are duo, flower and sloted forms and paired with a screw of 4.5 mm diameter. The plate and screw is made of SUS316L. A maximum load of 550 N is applied for each variation of plate design. The results are presented in terms of deformation and stress for both plate and screw. Numerical results show that the sloted plate is the best among the considered designs, from which the produced stress is below the material yield stress for almost all configurations.
