The beam loading device which is used to amplify the vertical load on the shear box assembly can receive up to 50 kg of weight. The total load on the specimen can reach up to 5 kN (5000 N).

The machine accepts 60 mm square, 100 mm square, 60 mm dia. round, 100 mm dia. round and 2.5 inc. dia. round shear box assemblies. All shear box assemblies are designed to contain water that surrounds the specimen. The Assemblies consist of a shear box with a rigid wall square or round hole complete with a vertical loading pad grooved back face, a grooved retaining plate, 2 pcs. porous plates, 2 pcs. plane grids and 2 pcs. perforated grids.

The shear machine is driven by high resolution servomotor and gear box assembly. Speed range is fully stepless variable over the range 0.00001 to 9.99999 mm/min for both direction( forward and reverse). After test the reverse speed is 10 mm/min.). 5 kN load cell is used for load measurement. 10 x 0.001 mm and 25 x 0.001 mm sensitivity linear potentiometric transducers are used for vertical and horizontal displacement measurements respectively. Displacement limits are controlled by limit switch.

Shear Box Assembly, Slotted Weight Set and other optional  accessories including specimens cutter and extrusion dolly should be ordered separately

BC100 Unit

The BC100 TFT Graphic Display Data Acquisition and Control Unit is designed to control the machine and processing of data from load cells and displacement transducers (fitted to the frame of the machine or additional frames).

All the operations of Data Acquisition and Controls System BC 100 TFT are controlled from the front panel which consists of a 800x480 pixel 65000 color resistive touch screen display and function keys. Three analogue channels for load cells and  displacement transducers.

The BC 100 TFT has easy to use menu options. It displays all menu option listings simultaneously, allowing the operator to access the required option quickly to activate that option or enter a numeric value to set the test parameters. The BC 100 TFT digital graphic display allows real time Load vs. Displacement or Stress vs. Displacement graph. The advanced functions for data base management provide an easy navigation of all saved data. The test results certificate includes all descriptive information. Therefore, test parameters can be set and details about the test carried out such as customer details, test type, specimen type, user info and other information required can be entered and printed out as well as test reports and graphs. Also, all minor revisions can be implemented upon request. The Software calculates both the maximum and resilient shear stress.

After three runs, the software calculates the cohesion value “c” and shear resistance angle”φ”  by using the best straight line fit.

Main Features

Consolidation

  • 25 pairs of time-vertical displacement values are written to memory.
  • The memory is configured as saving a maximum of 1000 tests.
  • The vertical displacement value can be tared prior to recording.
  • The analogical channel reading vertical displacement has 260000 points effective resolution.
  • The memory can be exported to PC software.

Shear

  • User can select 3 different test types:
    •  The machine run with the speed determined by user to the direction of shear and stop when the load decreases.
    •  The machine run with the speed determined by user to the direction of shear and stop when it reach the horizontal displacement value which is also determined by the user at the beginnig of the test.
    •  The machine run with the speed determined by user to the direction of shear and returns to opposite direction with the same speed when it reach the horizontal displacement value and then stop  when it reach the home position.The horizantal displacement  value is determined by the user at the beginnig of the test.

Data Acquisition & PC Software

The Utest Direct and Residual shear software is developed according to ASTM D3080, BS 1377:7 and AASHTO T 236 standarts to use with UTS-2060 Machine. Direct residual and shear software consist of two sections. First section is used for the consolidation of the sample prior to shear.

The second section of the software is capable of performing three different types of test. The first type of the tests is to move the machine with the speed determined by user until a load failure happens. On the second type of test the user can set a speed and a horizontal displacement and the test will continue until the machine reaches set value.On the last type of test, the machine can be configured as going to a set horizontal displacement value with the speed determined by user and return to opposite direction with same speed until the home position. And also the number of cycles,forward/reverse speeds and displacement for the measurement of residual share may also be programmed. The software supports 5 different normal load values in order to calculate cohesion values. Prior to the test normal load value must be entered to the software. The normal stress value would be calculated respect to normal load and sample size automatically. The software supports both square type and round type samples. For both samples the area might be calculated by directly or by using the net area caused by horizontal displacement. The net area method is especially important for critical samples on academic literature. When the test is completed max and resilient stress values are recorded. The normal load versus max stress pair is used for calculating the cohesion value and angle. At least 3 loading with different normal loads are required for this property. One can set test speed, axis values etc. through the setup of the software. The results can be submitted as a report or can be exported to Microsoft Excel for advanced reanalyze procedures.
