... In order to assess the effect of frequency on the dynamic response of clay, a modified resonant column/torsional shear apparatus was employed to test undisturbed samples of marine clay at various frequencies. Details of the modified apparatus are described and test results over a wide range...

... This paper describes a series of experiments performed on non-granular materials. The experiments consisted of performing different dynamic tests in the laboratory and the field, and comparing their moduli measurements. Torsional resonant column, torsional shear and resilient modulus tests were...

... both static and dynamic conditions, help illustrate the wide variety of stress paths these devices are capable of producing. KEY WORDS: hollow cylinders, torsional shear, stress paths, constitutive equations, anisotropy The solution of complicated soil engineering and soil-structure interaction...

... A review and evaluation of the advantages and limitations of laboratory equipment for measuring the shear strength of soils are presented. Equipment evaluated include direct shear, torsional shear, simple shear, triaxial, multiaxial (true triaxial), plane strain, hollow cylinder triaxial...

... condition that stresses and strains be homogeneous within the test specimen, and they allow tests to be conducted over a wide range of moisture contents. The specimens are subjected to oscillatory torsional shear deformations, and the moment response is measured; with the use of the specimen geometry...
