Applications of the New Approach to Resonant Column Testing
Geotechnical Testing Journal, 2015 Abstract For more than 50 years, the resonant column test has been used to measure the shear modulus and damping of soils for shear strains ranging from 10−5 % to 0.5 %. For most soils, the test is non-destructive, and tests may be performed on the same specimen at multiple confining stresses simulating in situ conditions from near ...

Torsional and flexural resonant column testing of grouted sands
Soil Dynamics and Earthquake Engineering, 2020Abstract Torsional and flexural resonant column tests were conducted on sands grouted with a fine cement and the effects of confining pressure, strain, grout water-to-cement ratio (W/C) and sand grain size and shape were evaluated. Both types of excitation were applied on a single grouted sand specimen without causing specimen failure.

Resonant Column Tests and Nonlinear Elasticity in Simulated Rocks
Rock Mechanics and Rock Engineering, 2017Rocks are generally regarded as linearly elastic even though the manifestations of nonlinearity are prominent. The variations of elastic constants with varying strain levels and stress conditions, disagreement between static and dynamic moduli, etc., are some of the examples of nonlinear elasticity in rocks.

Effect of Slenderness Ratio of the Specimen on Resonant Column Test Results
Journal of Testing and Evaluation, 2020 Abstract To investigate the effect of the slenderness ratio (L/d) of the specimen, resonant column (RC) tests were conducted on dry sand specimens by using three different values of L/d, namely 2, 3, and 4, keeping the same diameter (d = 50 mm) to measure the shear moduli and material damping associated with the shear strain varying ...

Nonlinear vibration analysis of the resonant column test of granular materials
Journal of Sound and Vibration, 2017Abstract This paper theoretically analyzes the nonlinear torsional vibration of a granular material specimen in the resonant column test (RCT). The RCT is a material testing method that has been well established in geotechnical engineering. The test provides some important dynamic properties of granular materials including the shear wave speed ...

Pore Pressure Buildup in Resonant Column Tests
Journal of Geotechnical Engineering, 1984Resonant column tests were performed on fully saturated and dry hollow cylindrical and fully saturated solid cylindrical specimens of Monterey No. 0 sand of 60% relative density subjected to 96 kPa confining pressure. The hollow specimens were tested by torsional excitation and the solid specimens by longitudinal excitation.

Resonant Column Testing of Agricultural Soils
Transactions of the ASAE, 1988ABSTRACT REMOLDED cylindrical specimens and minimally-disturbed cylindrical samples of three types of agricultural soils were tested in a torsional-type resonant column device. The soils were tested at confining stresses close to zero to simulate field conditions.

New Approach to Resonant Column Testing
Geotechnical Testing Journal, 2013Abstract This paper describes a new type of torsional resonant column device that has a quasi-fixed base and free top. In this device, a relatively rigid torque transducer is placed between the bottom platen and the fixed chamber base. A large capacity torque motor excites the top platen.
