Influence of particle shape on small-strain damping ratio of dry sands
This study reports on the significance of particle shape on the small-strain damping ratio of dry sands in shear ( D s,min ) through a comprehensive set of torsional resonant column tests. Sands with a variety of grain shapes prepared at variable initial densities are studied. The samples are subjected to torsional resonant column tests under isotropic confining pressures ( p ') ranging from 50 to 800 kPa. Small-strain damping ratios are derived based on the free-vibration decay mode of the samples and the results are compared with the half-power bandwidth method. The effects of grain size distribution, particle shape and effective confining stress on D s,min are thoroughly discussed, and a new model for the prediction of small-strain damping ratio of dry sand is proposed.
