S0125/SM/VC - Automated system for direct shear test. SOILMATIC VC
Horizontal shearing can be applied at a specified rate of deformation or at a specified rate of horizontal force change.
Proetisa’s automated direct shear apparatus is a universal shear system capable of performing the consolidation, drained and undrained direct shear or residual shear stages in a completely automated way.
Constant volume condition during the shear
The Automated system for direct shear test is a universal shear system capable of performing the consolidation and shear phases of a direct simple shear test under full automatic control.
The direct simple shear device is a way to measure undrained shear strength of soils that reflects the average shear strength mobilized in the field during failure of embankments on soft soil foundations and deep excavations in clay The test generates a fairly homogeneous state of shear stress throughout the specimen, which provides initial stress condition, stress path, and deformation configuration that models numerous field loading conditions more closely than any other test systems such as triaxial.
The system consists of a computer-controlled unit that utilizes motors to apply the vertical and horizontal loads to the soil specimen.
The system is capable of running a consolidation phase automatically.
Horizontal shearing can be applied at a specified rate of deformation or at a specified rate of horizontal force change. The constant volume condition during the shear is maintained through a closed loop computer control with the vertical displacement sensor as the feedback. The system is capable of displaying the current status of a test and graphically portraying the progress of the test in real time. The system includes the capability for the operator to alter the test process and conditions at any stage of the test.
Features and advantages
