Abstract
In this study the effects of frequency on damping behavior of dry sand were examined. To study the effects of frequency, two mechanical models were proposed and evaluated for interpretation of the cyclic torsional shear testing results. Cyclic torsional shear tests were performed on dry sand specimens for the frequency range of 0.1-20Hz. It is found that the frequency effect on damping properties of sand is relatively significant, and thus the damping appears to be nonhysteretic. Finally, a new combined damping model is proposed for describing the damping behavior of dry sand observed in this research. Copyright © 1996 Elsevier Science Limited.
