Among the biomaterial applications, the Total Hip Replacement (THR) method is the most successful. Many types of artificial hip joints are available in the commercial market. Various types of material and design can be selected to suit the needs of the patients. One of which is the design with fenestration type on the hip stem. In terms of materials, Titanium and stainless steel are the ones commonly used in hip joint replacement. In this paper, the effects of fenestration hip stem on mechanical behavior have been studied using the finite element analysis. Several hip designs, i.e., the hip joint without fenestration, hip joint with fenestration slot, hip joint with fenestration big loop, and hip joint with fenestration multi-loop, were considered in this study. All models were applied using Autodesk inventor model. Static structural analysis was performed using ANSYS to conclude at the best fenestration. Results showed that for Ti-6Al-4V material, design with many loop fenestration has the lowest stress than others, with the result obtained is 495.46 MPa. However, the artificial hip stem with slot fenestration has the smallest deformation with the least difference in value compared to other designs with distortion 0.54808 mm. In addition, the design that produced the higher stress von-Misses was big loop fenestration 526,28 MPa. In conclusion, it was found that all four designs indicated lesser stress values than the yield strength. © 2020 The Authors. Published by ELSEVIER B.V.
