DESIGN ANALYSIS AND FABRICATION OF BIOMEDICAL IMPLANT USING AL-ZN-MG/CU PARTICLES REINFORCED METAL MATRIX COMPOSITES

In medicine, prosthesis is an artificial device that replaces a missing body part, which may be lost through trauma, disease, or congenital conditions. Prosthetic amputee rehabilitation is primarily coordinated by a prosthetics and an inter-disciplinary team of health care professionals including surgeons, physical therapists, and occupational therapists. To improve the life quality of an above amputee, it is widely accepted that a prosthetic is one of the most essential assistive technologies to allow him/her to regain mobility. In addition to the stability, comfort, appearance and ease of use of the prosthesis, the safety is another important design consideration. The main aim of this work is to simulate to guarantee that knee prosthesis is able to survive a random severe load and has a sufficient fatigue life. Knee prosthesis is modeled in 3D modeling software CREO. The load acting on the knee is half of human body weight (considering the weight of human is 60 kg, 90 kg and 120 kg). Static and fatigue analyses is done to determine the stresses and fatigue life of the prosthesis by varying the loads. The materials used for comparison are metals Stainless Steel, Titanium, Cobalt chromium-based alloy and composite material(al-mn-mg) alloy with mixing of copper as powder. Analysis is done in Ansys
