Prediction of crack propagation direction in the cemented total hip prosthesis

Charef D., Serier B.

Mechanics and Mechanical Engineering

2017

Vol. 21, nr 3

703--716

The major inconvenient of the Poly methyl methacrylate (PMMA) is the crack formation; this phenomenon takes place during the polymerization process which is the result of an exothermic chemical reaction. In this context, this study aims to predict the behavior of macros cracks situated in the most heavily loaded sites in newly used bone cement. In fact, the prediction of crack propagation directions in bone cement during exercising the most practiced activity by patients allows determination of the most favorable cracking directions and subsequently provides orientations for the studies aiming to fight against this phenomenon.
