Research ArticleOpen accessIn the abstractComparison between Brain Tissue Gray and White Matters in Tension Including Necking PhenomenonSina Mehdizadeh, Mehdi Khoshgoftar, Siamak Najarian et al.Characterizing the differences between the mechanical properties of brain tissue gray and white matters is of importance in biomechanics of brain tissue and may find a variety of different applications in medicine. In this study, a comparison has been made between mechanical behavior of bovine brain tissue white and gray matters. Through a linear elastic theory and using Bridgman method, … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,839 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Biomechanical Composite Model to Determine Effective Elastic Moduli of the CNS Gray MatterMehdi Khoshgoftar, Siamak Najarian, Farhad Farmanzad et al.Brain tissue is a heterogeneous material with complicated microstructural features. Models based on microstructure can lead to more accurate and physically realistic predictions of mechanical characteristics of brain tissue. A two-step Mori-Tanaka/Voigt homogenization procedure is implemented into a 3D microstructurally-based multi-phase composite model, composed of randomly-oriented elastic axons, dendrites and neuronal cell bodies surrounded by an elastic matrix. The effects … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 7,775 accessesView PDFCite
