Dynamic (Cyclic) Simple Shear Testing System


The VJ Tech Dynamic (Cyclic) Simple Shear Testing System (DSSS) has been designed to provide all the basic functions required to carry out cyclic simple shear testing on soil characteristics in dynamically changing conditions. It allows direct investigation of the shear vs. stress strain in drained and undrained situations. The System incorporates the Dynamic Shear System apparatus (with appropriate transducers) controlled from a PC over a standard network connection using a Dynamic Servo Controller for high speed servo control for cyclic motion. An Automatic Pressure Controller is used for confining Back Pressure and user friendly software provides the necessary Test configuration, control and data acquisition.
