Because it can simulate a broad range of field loading conditions, the cyclic simple shear apparatus is often used in soil dynamics research.
A simple cyclic shear has a planar strain. A shear strain occurs when the bottom of the sample travels horizontally. Because the sample’s diameter remains constant, any volume variation is explained by vertical platen movement. The system consolidates and then shears a sample under continuous volume.
The system’s main parts are as follows:
Transducer Vertical.: This transducer is calibrated to 2.5 mm for sample height control. Precision 1 m.
Signal Conditioning Inline.: This normalizes all transducer outputs, enabling them to be switched across channels without recalibration.
