Integration of multi-objective structural optimization into cementless hip prosthesis design : Improved Austin-Moore model

Kharmanda, G. LU (2016) In Computer Methods in Biomechanics and Biomedical Engineering 19(14). p.1557-1566
Abstract

A new strategy of multi-objective structural optimization is integrated into Austin-Moore prosthesis in order to improve its performance. The new resulting model is so-called Improved Austin-Moore. The topology optimization is considered as a conceptual design stage to sketch several kinds of hollow stems according to the daily loading cases. The shape optimization presents the detailed design stage considering several objectives. Here, A new multiplicative formulation is proposed as a performance scale in order to define the best compromise between several requirements. Numerical applications on 2D and 3D problems are carried out to show the advantages of the proposed model.
