The GDS Large Diameter Cyclic Triaxial Testing System (LDCTTS) is hydraulically actuated with a large diameter triaxial cell suitable for testing samples with large particle sizes such as railway ballast. The system is capable of both monotonic (static) and dynamic triaxial tests as well as other advanced triaxial tests usually expected from a GDS system. Using GDSLAB software with optional test control modules, GDSLDCT can run tests such as stress paths, slow cyclic, dynamic cyclic and K0, all under PC control. Technical specification: Displacement range = 100mm. Displacement resolution = 16bit (i.e. <2μm). Displacement accuracy = <0.15% (i.e. <0.15mm). Axial force resolution = 16bit (i.e. <0.4N for 10kN load cell, <1.5N for 40kN load cell). Axial force accuracy = <0.1% of load cell range (i.e. 10N for 100kN load cell). Control data points = 10,000points/sec. Maximum saved data points = 100points/cycle. Compliance with international standards.
