Currently, the Spinal Instability Neoplastic Score system is used in clinics to evaluate the risk of fracture in patients with spinal metastases. This method, however, does not always provide a clear guideline due to the complexity in accounting for

How to determine composite material properties using numerical homogenization

Autor: Erik Andreassen, Casper Schousboe Andreasen

Publikováno v: Andreassen, E & Andreasen, C S 2014, ' How to determine composite material properties using numerical homogenization ', Computational Materials Science, vol. 83, pp. 488-495 . https://doi.org/10.1016/j.commatsci.2013.09.006

Numerical homogenization is an efficient way to determine effective macroscopic properties, such as the elasticity tensor, of a periodic composite material. In this paper an educational description of the method is provided based on a short, self-con

Non-destructive 3D micro-computed tomography (microCT) based finite element (microFE) models are used to estimate bone mechanical properties at tissue level. However, their validation remains challenging. Recent improvements in the quantification of
