dc.description.abstract | In this article, the human lumbar spine region, affected by osteoporosis, L4 vertebra modelling and stability analysis are presented. Tissue degradation problem was examined. Spatial numerical model in SolidWorks computer program environment was done. Numerical experiment was done in finite element method in ANSYS Workbench environment. This article is also given with calculation results, when the compression force and the compression force with tension are applied. Model’s cases for loss of load bearing capacity are examined with simulating aging and osteoporosis effects, which occurs with aging of the tissue. Degradation of the tissue is modelled while applying expressions determined with empirical approach, which link dependency between mechanical properties and porous bone density. | eng |
