Dynamic Simple Shear with Confining Pressure

The VJ Tech Dynamic Simple Shear Apparatus with Confining Pressure utilises 2 electro mechanical dynamic actuators for applying the vertical and horizontal loads to the sample which is held under Pressure in an adapted Triaxial type Cell or within Confining Rings and no Confining Pressure. The vertical and horizontal displacements are measured with Encoders which are part of the servo motors. The maximum range of travel in each axis is protected by a limit switch and each strain rate is easily set from the PC. The controlling software (Clisp Studio DYNADSS-C) enables all stages (Saturation, Consolidation (Isotropic, Anisotropic or K0), and either Static Loading, Cyclic Shear (Stress or Strain) or Liquefaction) to easily be set up and run.
