Shear modulus and damping ratio of grouted sand
Soil Dynamics and Earthquake Engineering, 2004An experimental comparative study of three different grouted sands in terms of their effects on the values of two dynamic properties is presented. The dynamic properties studied are the shear modulus and the damping ratio which are determined with resonant column tests and cyclic triaxial tests.

Pneumatic suspension damping characterisation with equivalent damping ratio
International Journal of Heavy Vehicle Systems, 2012The damping property of a pneumatic suspension with orifice-type fluidic resistance is characterized in this study. The nonlinear and linear models for the suspension system are first formulated and experimentally verified. The verified linear model is employed to derive a new pneumatic damping measure, equivalent damping ratio, based on which a ...

Damping-ratio measurements by the spectral-ratio method
Canadian Geotechnical Journal, 2006In this paper, bender elements are used as sensors to measure the damping ratio of soil by the spectral-ratio method. The results of numerical and physical experiments suggest that adequate measurement precision can be achieved by reducing the two types of inherent biases arising from (i) the near-field effect and (ii) the different transfer functions ...
