Shear strength tests on soil samples are conducted using triaxial test equipment. One of the most adaptable soil strength tests in geotechnical engineering is triaxial shear strength. It allows for the control of specimen stresses in perpendicular directions and is more complicated than a direct shear test.
Additionally, sample drainage can be managed, and specimen pore pressure can be observed. Test specimens may be prepared as remoulded samples or drawn from an undisturbed sample. The specimen is placed within a chamber that is fluid-pressurised and covered in a protective latex membrane before being coupled to a load frame.
The axial deformation rate is maintained constant while the sample is vertically loaded and sheared. These evaluations establish the soil’s strength and its stress-strain connection.
To determine the mechanical characteristics of granular materials like soil, sand, and clay, triaxial testing is used. A sealed cylindrical soil specimen with a height-to-diameter is typically enclosed in a pressurised cell to replicate specific stress conditions.
The shear strength parameters of the specimen are then determined by repeatedly shearing it until it fails. The specimen is sheared mostly under compressive conditions after being initially saturated, then consolidated, and finally sheared. We provide a broad selection of testing tools to suit the various requirements.
The Global Triaxial Testing Equipment market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
A triaxial system with an electro-mechanical actuator installed on a beam, the GDS Enterprise Level Dynamic Triaxial Testing System (ELDYN) is based on an axially stiff load frame.
The ELDYN was created to meet the need for a more affordable, simpler dynamic triaxial testing system in the geotechnical laboratory testing market while maintaining delivering the high performance levels that GDS’s clients have come to expect.
To investigate the mechanical characteristics of MHBS at various methane hydrate (MH) saturation levels, the servo-controlled HYDRATEST system performs triaxial tests on methane hydrate-bearing-sediments (MHBS) under low temperature (below freezing) and high pressure circumstances.
Temperature, pore pressure, confining pressure, and hydrate saturation can all be used to express the mechanical properties of MHBS. Triaxial tests are used to assess the Young’s modulus, cohesion, and internal friction angle of sediments generated in a lab that contain hydrates. A hydraulic compression frame is used in the system to apply axial loads of up to 100 kN to the specimen.
