Shear Moduli of Metal Specimens Using Resonant Column Tests

Journal of Testing and Evaluation, 2019
Abstract The shear moduli of cylindrical metal specimens were determined by performing resonant column tests in a torsional mode of vibration. The tests were performed on four different metals, namely (i) aluminum, (ii) brass, (iii) copper, and (iv) mild steel.

Resonant Column Testing of Sands with Different Viscosity Pore Fluids

Journal of Geotechnical and Geoenvironmental Engineering, 2000
The effect of pore fluid viscosity on the stiffness, damping, and liquefaction characteristics of sands was investigated to assess the potential contributions to a centrifuge model seismic response for soils saturated with high-viscosity pore fluid.

Radial Strain Measurements in Resonant Column and Torsional Shear Tests

Transportation Research Record: Journal of the Transportation Research Board, 1996
During resonant column and torsional shear tests using a Stokoe device, conventionally only the change in height of the specimen is measured. To obtain the change in diameter of the specimen, a relationship between radial strain and longitudinal strain is assumed.

Characterization of Warm Mix Asphalt through Resonant Column Testing

Journal of Materials in Civil Engineering, 2015
As the usage of warm mix asphalt (WMA) has gained popularity in recent years, the need has arisen for more characterization techniques and performance prediction through accelerated laboratory testing. This paper presents an experimental study on the shear modulus and damping ratio of asphalt specimens prepared using three WMA technologies: Evotherm ...

Effects of Imperfect Fixity in Spring-Top Resonant Column Tests

Geotechnical Testing Journal, 1990
Abstract A two-degree-of-freedom model is proposed to study the effects of imperfect fixity at the active end of the spring-top resonant column apparatus. A computer program using the SYMPHONY spreadsheet is developed to calculate the dimensionless frequency, F, from which the modulus can be determined.

Control, acquisition and analysis of resonant-column testing using an automated program

2011
A Resonant-Column apparatus was modified by replacing the internal generator by an arbitrary function generator. A PC oscilloscope was used to acquire both the input current in coils and the vibration response of the system. Software developed in LabVIEW® controls the equipment, acquires data and then processes the information, computing the ...
