We operate an electromechanical direct/residual shear system capable of applying up to 2,500 lbf (11 kN) vertical and horizontal load capacity, and deformation rates of 6 x 10-6 to 33 mm/min (0.1 nm/s - 16.67 μm/s). Shear testing can currently be performed on 1" and 2” round samples. The apparatus is configured to record and store normal and shear loads and displacements (4 channels) with the ability to record additional sensors/channels.
