Description

This device combines a  temperature control and advanced direct shear testing capabilities and empowers the users to investigate the temperature dependent behavior of rock fractures, providing critical insights for applications in mining, geothermal energy, and civil engineering particularly in contexts where rock stability is concern.



Additionally, the study of the instability of a rock block caused by global temperature fluctuations and human activities in permafrost areas can be conducted using this device. The temperature controlling system can control the temperature of the sample in the range of -20°C up to +150°C with a temperature resolution. The controlling of temperature is controlled by main software of the machine.


The combined modular direct shear and triaxial test system is designed to determine the shear strength of intact, joint rock or concrete samples. Different sample sizes (e.g. cylindrical, prismatic, cubical or irregularly shaped) can be tested by our system.



The Geotechnik Wille® modular rock shear testing system combines the opportunities of a triaxial rock testing and a direct shear system.



Due to its modular approach, the user is enabled to upgrade the system to a fully equipped triaxial device.



The rock shear testing system is able to perform static and dynamic loading tests on different rock samples up to 200 mm with an axial force up to 3,000 kN and a shear force up to 1,000 kN.  Different sample sizes are available per request. The complete system is fully automated and controlled by our flexible and programmable GEOsys Software.



As an option, the system can be equipped with an ultrasonic system with different transducers for P (compression waves), S1/S2 (polarized shear waves) and acoustic emission.



Various other sensors and different materials as well as experiment options (e.g. permeability) are available. The system can be fully customized to the needs of the user and the scientific problem.


Digital Controller

Digital High-Speed High Resolution Expandable Real Time Control and data acquisition System to 10KHz and 24 bit resolution. The Dynamic controller is suitable for screw driven instruments(electromechanical) , hydraulic instruments with a valve driven with ±10 Volt and variety of sensors e.g. load cells, LVDTs, strain gauges, extensometers, thermocouples and etc.

The multi-functionality of the controller allows a modular design of the measurement and control parameters (sensors) via intelligent sensor plug, which store the calibration parameters, thus depending on the application can be used flexibly.

Software

GEOSYS Software

GEOsys is a multi-functional and modular controlling and data acquisition software in Windows. It allows for the simple programming of complex user defined test sequences via structured Windows instructions on a graphi cuser interface.

GEOsys utilizes a flexible, programmable system that controls test appliances that coordinate various test operations. The flexible operating panel provides tools to configure the appliance,  editors to carry out load procedures, and functions for analysis, presentations and logs. The software is designed to support a modul arstructure for the test environment so as to enable a flexible configuration and thus fulfil the specific requirements of the company.


The important key feature of this software is the ability to allow users to simply and freely program standard or complex test sequences with structured Windows operations via a graphic user interface.

Thanks to the wide range of abilities Geosy soffers, it is not only compatible with our products, but it can also be used with hardware from other manufacturers, providing data acquisition and test controlling for hard- ware of a similar or more advanced standard.

Direct Shear Test Module
GEOsys is designed for closed-loop controlled static & Dynamic tests for all test applications in material testing, such as stress-controlled, strain-controlled, all stress paths, loops, any kind of waveforms like sine, rectangle, triangle, and predefined waves. It is controlling and data acquisition software and also has different modules to run tests according to ASTM or ISRM methods.
The direct Shear Module runs conventional shear tests, residual and also incremental tests. It also runs Single- or multistage -shear testing at several levels of normal stress and various rates of shear deformation.
