Vibration of a tubular bone in axial planes

By considering the material nonhomogeneity as well as the dissipative material behaviour of osseous tissues, the paper is devoted to a study of a vibrating tubular bone specimen. In conformity to recent experimental observations, nonlinear variation of the elastic moduli of bone tissues with volume density, has been paid due attention. Computational results indicate that while linear variation of the material parameters with volume density of bone tissues does not bring about any appreciable change in frequency of the bone specimen, nonlinear variation alters the frequency spectrum to a considerable extent.
