Temperature Controlled Cyclic Direct Shear Apparatus
THM Cyclic Direct Shear Apparatus
This series of stand-alone electromechanical cyclic shear testing devices are designed and manufactured to perform static and cyclic shear tests on soil under different temperature conditions.
Many tests require temperature controlling of specimen either for high temperature or for low temperatures and this requires new designed system which would be able to avoid any temperature gradient in sample during tests and make a unique constant temperature condition for the period of testing.
The system can be customised in variety test conditions e.g. Static or Cyclic loads with electro-mechanical motor, different sample sizes either in simple shear or direct shear test format, Low temperature tests or/and high temperature tests which all can be configured together to meet the test requirements.
The temperature controlling system can control the temperature of sample in range of -30°C up to +200°C.

- Safety functions to prevent overload and overtravel
- Direct operation of the device by a PC with controlling software (communication protocol is available)
- Different types of loading waveform can be given to the sample e.g. Sinusoidal, Square, Triangular, Haversine, Saw Tooth, Inverted Saw Tooth, Rectangle, and User Defined wave forms.
- High speed dynamic controller for cyclic tests for monitoring of measured values and test procedures (2,5KHz or 10 KHz)
- Real-time data and graph display
