New Product Development: A Multi-directional dynamic cyclic direct simple shear apparatus.
A significant majority of test apparatuses traditionally used in soil laboratories shear soil elements in a single direction only. Examples include the direct shear apparatus, in which a test specimen is sheared in a single horizontal direction following application of normal stress, and the triaxial apparatus, in which soil elements are compressed or extended vertically following completion of saturation and consolidation. Such apparatuses may be termed uni-directional, as the direction of shearing is fixed to one specific axis.
