dc.description.abstractIn total hip arthroplasty (THA), has been over time, an exponential growth of studies with Finite Element Method (FEM) computational simulation in order to obtain the prosthesis with a longer life duration, however just a few in COMSOL Multiphysics software. The main goal of this study was to perform stress and strain studies under different load conditions for the titanium and cobalt-chromium alloys in cementless prostheses. In software COMSOL Multiphysics, 3D models of a femur and a Lubinus SPII implant with two different alloys, were tested. Two COMSOL studies were carried out, one stationary and the other dynamic (time-dependent) for both material’s prostheses. In a stationary study for walking activity, the titanium alloy implant showed an equivalent von Mises stress maximum level of 0.9 × 108 Pa at the contact between the implant and the bone, having been found a similar value by other investigators ( Prasad, Karthika, et al. “Metallic biomaterials: current challenges and opportunities.“ Materials 10.8 (2017): 884.). In the Co-Cr alloy prosthesis, the equivalent von Mises stress for walking activity was like titanium alloy. The shear stress and normal stress of the two prostheses were compared. In the dynamic study for climbing stair activity the equivalent von Mises stress was greater 7.5 times than in walking activity for Co-Cr alloy implant. The maximum stress (stationary and dynamic) of the titanium alloy implant is slightly higher than the Co-Cr alloy implant, which indicates that Co-Cr prostheses react better when subjected to loads.pt_PT
