The VJ Tech Dynamic (Cyclic) Simple Shear DSS system is engineered to deliver reliable, repeatable, and standards compliant simple shear testing for both academic research and commercial laboratories. Designed with both precise electro-mechanical control and integrated test automation, the DSS provides high-quality static and cyclic simple shear testing, delivering loading accuracy and data integrity confidence.

The VJ Tech Dynamic Simple Shear Apparatus with Confining Pressure (DSS-C) 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 a sample contained within Confining Rings and no Confining Pressure

VJ Tech’s Hollow Cylinder System Test subjects the sample to four distinct applied stresses: Axial, Torsional, Inner, and Outer confining stresses. This provides the specimen with four degrees of freedom for deformation. The sample is prepared as a thick hollow cylinder, securely positioned between two rigid platens.

Wykeham Farrance’s Resonant Column is a versatile system that combines Resonant Column and torsional shear tests into one convenient device for evaluating Shear Modulus and Damping Ratio. It includes: current-driven motor that applies torsional load to the sample a series of transducers with signal conditioning cell and back pressure electro-pneumatic control system data logger.
