Abstract: The dynamic properties of dry sands from triaxial tests represented as values of modulus and damping were investigated and compared with simple shear test results for the same material using equivalent test parameters. It was confirmed that for both types of tests the effects of strain amplitude, relative density, and confining pressure are similar. Dynamic triaxial and simple shear modulus values can be related at the same shear strain amplitude and at equivalent confining pressures. A correlation curve is presented. The difference between triaxial and simple shear damping values is insignificant and the results may be used interchangeably at equivalent shear strain amplitudes.
