Description

Fully automatic closed-loop controlled dynamic ring shear apparatus applicable for highly precise ring shear tests to measure shear strength parameters at failure and residual shear with a big frequency of 20 Hz.


This development includes our experience in details of wall friction compensation and guidance of the shear boxes.


Applicable with free selectable and programmable closed-loop controlled stress-paths with stress, strain and height / volume controlled test procedures.

Standard
Feature

• The complete ring shear box system is made of stainless steel including upper and lower shear rings, porous ring plates with or without ribs, load piston and water receiver for saturated conditions

• Continuously adjustment of the inner and outer shear band after consolidation, free of tilting

• Sophisticated robust construction combined with high quality mechanic and electronic

• components of industrial standard

• Closed-loop controlled normal stress by a load cell

• Closed-loop controlled shear strain rates by high resolution transducer

• High resolution data acquisition system with high quality transducers for shear stress, normal stress, shear strain and axial strain

• The device can be operated by the touch sensitive keypad or by PC control with adequate software

Software

GEOSYS Application Software

GEOsys is multifunctional and modular fully automatic controlling and data acquisition software available for WINDOWS, LINUX or MAC OSX , which is the universal software for our products. The software performs the CRS tests per as ASTM D4186 and also other tests which are listed in other pages could be run by software.


Main Features

• User defined multiple Incremental loading & unloading

• User defined Saturation cycles (ramp and check)

• Performs all consolidation tests

• Ability to move automatically to next stress level

• The software can be programmed for multiple incremental loading stages

• Optional swelling pressure test

• Limit Setting

• Complete recording and displaying test results in real time

• Live test graphs on screen

• Automatic calculation on back ground

• Fully automatic testing procedure and monitoring via PC control, 12 devices simultaneously and independent

• Possibility to export test results to Microsoft Excel

• Integrated safety features are implemented in software

• Comprehensive status and error messages on the display/ software with number for traceability

Upgrade Option

• Pore pressure transducer

• Unsaturated test conditions including of automatic pressure con-troller or conventional pressure panel and confining pressure cell
