Dynamic (Cyclic) Simple & Direct Shear System

For prices: call +44 (0)118 945 3737 or Email us

The VJ Tech Dynamic (Cyclic) Simple & Direct Shear System has been designed to perform either Dynamic (Cyclic) Shear, Direct/Residual Shear or Direct Simple Shear tests.

The System incorporates 2 electro-mechanical actuators for Horizontal and Vertical movement, controlled from a Dual Axis Dynamic Servo Controller (DSC3000MM) via Ethernet or USB from a PC. The sample is contained within either a Direct Shear assembly or a Simple Shear assembly (interchangeable) as required. Load and Displacement are measured with transducers on both axes through the DSC3000MM and cyclic controlled tests can be carried out using Sine, Square, Triangular, Haversine, Saw Tooth, Rectangular or User Defined waveforms.

The software conforms to D6528-07 or BS1377 dependent on the test being performed.
