Abstract:
The vibratory unconfined compression tester (VUCT) for cohesive solids was studied using DMX and discrete element method (DEM) software. The vertical displacements of the spring, top cap mass and base, radial displacement of the sample at mid-height, and accelerations of the top cap mass and the base were measured. The top cap stress, axial, radial, volumetric and shear strains, and the work done by the top cap mass were calculated from these measurements. It was concluded that the maximum stress for each material is dependent upon the applied frequency of vibration.
