This paper focuses on the effect of morphology of bone tissue on processes of its deformation and fracture. For this purpose, three-dimensional unit cells of trabecular bone tissue were generated based on the scans of human distal tibial bone obtained with high-resolution peripheral quantitative computed tomography (HR-pQCT). Mechanical behavior of porous structure of trabecular bone was investigated under conditions of applied tensile and compressive loads employing a model of degradation of elastic properties, numerically implemented with finite-element analysis. The calculations were performed in Simulia Abaqus using the UMAT custom subroutine.
