The calculation results for the stress-strain state of model compact bone tissue samples differing in orientation of collagen-mineral fibers are presented for the case of axial compression. The results have shown that samples of different types have different non-uniform deformation in directions perpendicular to the compression direction, which is caused by the corresponding orientation of collagen-mineral fibers. The longitudinal modulus of elasticity of a sample with parallel orientation of collagen-mineral fibers is larger than the module of elasticity of a sample with the perpendicular direction of fibers by a factor of 1,5. The neighboring values of the longitudinal moduli of elasticity are typical for samples with variable direction of fibers and with the location of fibers at angles of $\pm45^\circ$.
Keywords: computer simulation, compact bone tissue, collagen-mineral fibers, stress and strain state.
