Modeling of TA6V Titanium Alloy by an Identification Strategy: Biomechanical Application

Abstract

AbstractThe applications of titanium alloys are traditionally present in the transport, particularly in terms of engines and turbojets. The major advantage of these alloys is mainly related to their good mechanical behavior including a good mechanical resistance under different stress conditions. The use of titanium alloys in the field of biomechanics, especially in bone prostheses, is an advantage due to their mechanical properties close to those of bone. This work is concerned with the study of mechanical behavior of the TA6V titanium alloy present in femoral stem of the total hip replacement (THR). To do this, constitutive modeling is proposed to identify the parameters of the material using CPB06 criterion taking into account the microstructural state of the material. The proposed approach provides a reliable model that could be implemented in finite element software. The obtained results can be used to study the mechanical behavior of the prosthetic structure when subjected to several combined solicitations.KeywordsTA6VTHRIdentificationCPB06Compressive loads
