CYCLIC TRIAXIAL TESTING MACHINE (Automatic) (T833)
Category: Soil

Product Code: T833
Category: SOIL
Sub-Category: CYCLIC
- Designed for determining cyclic strength (liquefaction resistance), small-strain shear modulus & damping, and resilient behavior of soils under repeated loading. Suitable for CU cyclic programs and pavement-style loading workflows.
- Fully automated triaxial platform integrating servo-actuated axial loading, dual pressure/volume control (cell & back pressure), and synchronized high-rate data acquisition for closed-loop control in load or deformation.
- Cyclic loading with sinusoidal control for ASTM D5311/D3999;
- End-of-test criteria configurable by cycle count, axial strain limit, or pore-pressure ratio (ru), with real-time plots of q–εa, Δu–N, and stress path to support rapid interpretation.
- Flexible specimen configuration with common diameters (38/50/70/100 mm), interchangeable caps/pedestals/porous stones, and optional local strain or bender-element kits.
