TL;DRAbstract

Abstract—Femur is leg bone of the human body undergoing more deformation. Being longest and heaviest in size, failure of femur neck is the most common among bone failures in human especially in woman. Orthopedic implantation is done in case of failure. Before implantation it is necessary to analyze the perfectness in case of its material property, size and shape, surface treatment, load resistance and chances of failure. Analysis is done for the stresses formed in femur implant of Ti-6Al-4V material under static loading condition using ANSYS software. Since each femur carries 1/2 the body weight, analysis is done for 25kg, 50kg, 100kg, 200kg loads, including the cases of patient carrying certain weight. From analysis it is found that the loads have no effect on failure of implant, since the values of stresses and deformation are very low. Thus failure of implant is maximum by wearing, corrosion and all due to improper material selection of implant. And based on the analysis it can be c
