    Notes: Abstract Dynamic analysis of the viscoelastic simple supported beam has been made in accordance with the relationship between stress and strain expressed by the simplest Voigt mechanical model, from which several analytic expressions have been obtained. It is shown that the reduction of the ratio of natural frequencies progresses with the increase of the exciting frequency for high modes (Tab.1). In the final part of this paper, the forced vibration of simple supported beam subjected to a random and harmonic excitation has also been dealt with, and the representations of the beam deflection have been derived.

    The compressive properties of long bones (1981)
    Springer
    Applied mathematics and mechanics 2 (1981), S. 733-742 
    Details
    ISSN: 1573-2754

    Notes: Abstract In this study, compressive tests of the bones along the axial direction have been carried out on some wet specimens of the right femur and humerus, from which there have been obtained the elastic modulus of femur E=9.98×109N/m2 and that of humerus E=11.37×109N/m2. Also comparisons and discussions have been made with reference to the available data reported abroad and at home. As indicated in this paper, bone tissues obviously possess viscoelastic properties. Their hysteresis loops are shown in Fig. 3 (a) and (b) and some mechanical phenomena observed during the test are illustrated elsewhere.
