Problem of determining soil properties in dynamic range of loading, in which inertia forces must be taken into account, is considered; analytical solutions for two models are presented; tests show that for shear strain amplitudes in order of 10-6 to 10-4, for confining pressures between 500 and 3000 psf and for frequencies less than 600 cps, viscosity should be assumed to decrease with frequency such that ratio, viscosity times frequency divided by shear modulus, is constant with frequency, in order to use model; values of this ratio for dry sand are given.
