Temperature Controlled Static Direct Shear Testing Apparatus (THM)
THM Static Direct Shear Testing Apparatus
This series of stand-alone electromechanical shear testing devices are designed and manufactured to perform 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 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.

GEOsys is designed for closed-loop controlled static & Dynamic tests for all test applications in material testing, such as stress-controlled, strain-controlled, 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 other standard methods. Depends on the requirement of the customer one or several modules would be delivered with main software, such as:
- Data Acquisition, processing, and device management (DPD) Module
- Consolidation Stage (Single stage, multiple stage or over consolidation mode)
- Temperature control module
- Static Direct Shear module Constant Normal Stress test
- Constant Normal Height test
- Constant normal stiffness test (CNS)
- Shear stress-controlled test
- Shear displacement control (forward and reverse)
- Calculation of shear stresses
