Abstract:

The paper discusses a non-resonance (NR) test method that uses measurements of the frequency response function between the applied torque and resulting angular displacement of the test specimen to determine the dynamic properties of material over a broad frequency range. Preliminary experiments on two soil specimens were performed to demonstrate the capability and advantages of the method. The proposed test method uses the same equipment commonly used for resonant column and torsional shear tests, but increases the frquency limit from about 2 Hz to 30 Hz by properly accounting for inertia effects. The foremost advantage of the NR method is its capacity to provide nearly continuous measurements over a broader frequency range for a variety of applications and for studying viscoelastic phenomena in soils.
