  • Title: Model for bone strength and osteoporotic fractures.
    Author: Gunaratne GH, Rajapaksa CS, Bassler KE, Mohanty KK, Wimalawansa SJ.
    Journal: Phys Rev Lett; 2002 Feb 11; 88(6):068101. PubMed ID: 11863854.
    Abstract:
    Inner porous regions play a critical role in the load bearing capability of large bones. We show that an extension of disordered elastic networks [Chung et al., Phys. Rev. B 54, 15 094 (1996)] exhibits analogs of several known mechanical features of bone. The "stress backbones" and histograms of stress distributions for healthy and weak networks are shown to be qualitatively different. A hereto untested relationship between bone density and bone strength is presented.
