Finite element analysis on prosthetic leg under different loads and flexion angles for medical applications
Abstract
Prosthetic legs (PL) are mainly used to perform leg amputations more easily. The design and performance of these legs mainly depend on the material selection and manufacturing methods. In the present study, alternative materials are considered for PL such as Al alloy, Ti alloy, Uni directional Carbon fiber epoxy (UDCFE), and combined composite material (CF, UDCFE and Ti alloy) to perform static and fatigue analysis . Static analysis was performed under four different load conditions 60 kg,70 kg, 80 Kg and 90 kg. Fatigue analysis was done under low cycle fatigue conditions. Theoretical calculations are evaluated at various inclinations of the foot 10°, 20°, and 30° with the ground. The results obtained theoretically are compared with Ansys results. The best material which gives the lesser value of deformation and lower damage factor is selected for the design. Further, experimental studies were suggested based on the results obtained from this work.
