Optimum Material Selection to Prosthetic Leg through Intelligent Interface of RSM and FEA

Abstract Prosthetic leg components support individuals with above knee amputations. Major focus should be done on its optimization part as the requirement includes light-weight structure that can withstand heavy loads. This work investigates the compatibility of various materials in prosthetic leg with material properties same as that of Structural Steel, Magnesium Alloy, Aluminum Alloy, etc. In this present paper the optimum material selection was being made by using proper interface between the FEM and also Response Surface Methodology. In the case of FEM the simulation was carried out for different material in ANSYS Workbench 15.0 with paying major concentration on the Factor of Safety which is influenced by the factors such as Density, Poisson Ratio, Compressive Strength, Young modulus. With proper selection of design in Box Behn-Ken method the Optimization is carried out for the effective compatibility of material in usage.
