A micro-finite element (FE) model of trabecular bone was reconstructed from a sequential of cross-section micro-CT image by converting bone voxels to brick elements. Eight regions of interest (ROIs) were extracted from to lumbar vertebra bone specimens of healthy and osteoporotic. The homogenization method and finite element method was employed to analyse the microspcopic trabecular bone. Bone tissue property was modeled as orthotropy material considering the biological apetite (Bap) crystallite orientation. This research focuses on the effect of morphological different between healthy and osteoporotic bones to the apparent elastic moduli. The change of degree of anisotropy was also discussed. Comparison of the calculated Young’s moduli in vertical axis with Keyak et al.’s experimental result showed good agreement and proved the reliability of the numerical model. 2015-02-23T08:56:02Z 2015-02-23T08:56:02Z 2014-02 Article Advanced Materials Research, vol.894, 2014, pages 167-171 1662-8985 http://dspace.unimap.edu.my:80/xmlui/handle/123456789/38985 http://www.scientific.net/AMR.894.167 10.4028/www.scientific.net/AMR.894.167 en Trans Tech Publications
