Open cell polyurethane foam compression failure characterization and its relationship to morphometry

Open cell polyurethane foams are often used as cancellous bone surrogates because of their similarities in morphology and mechanical response. In this work, open three different densities characterized from morphometric perspectives. The analysis micro-computed tomography images has revealed that the high density present greatest inhomogeneities. Those inhomogeneities promoted failure location. We have finite element models a tool to estimate elastic properties can be numerical modeling. Furthermore, we assessed anisotropic response foams, whose differences related found significant relationships between morphometry detailed information about morphometry, constants strength limits provided work interest researchers practitioners use these orthopedic implants cement augmentation evaluations.
