AUTOMATIC DIRECT RESIDUAL SHEAR MACHINE

The Automatic direct residual shear machine is capable of performing the consolidation and shearing phases of a standard direct shear and residual shear test under full automatic control.

The system consists of a computer-controlled unit that utilizes micro-stepper motors to apply the vertical and horizontal loads to the soil specimen. The system is capable of doing a consolidation process at 32 phase automatically.

Horizontal shearing can be applied at a specified rate of deformation or at a specified rate of horizontal force change, or at a specified set of force steps of a specified duration.

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.

The Automatic Direct Residual Shear Test Machine is supplied complete with;
• Load Cell 5 kN
• Vertical Displacement Sensor (10x0.001 mm)
• Horizontal Displacement Sensor (25x0.001 mm)
• PX6 Pro Color TFT Touch Display Supports 16M colors and supports 800x480 pixel screen resolution Data Acquisition Control System
• Software

Shearbox Assemblies, Slotted Weight Set and other optional accessories including cutting ring and extrusion dolly should be ordered separately.

Software
The digital graphic display shows real-time load-displacement or stress-displacement graphs. The software calculates both the maximum shear stress and the residual shear stress.

After at least three tests, the software calculates the cohesion value “c” and the shear resistance angle “φ” using the best-fit tangent to the Mohr circles.
