Home Test Methods Rock Testing Stress Paths Rock Test Equipment Stress Paths Rock Test Equipment In a triaxial test, a stress path is described by any change in stress state in any direction on a sample. To be able to perform a stress path test it is generally considered that control of both the axial stress and the radial stress is required. With this level of control, linear paths may be controlled of either axial stress and radial stress, p and q (deviator stress), or s and t paths. Please note: Some apparatus may require additional components or software modules to perform certain tests. The following rock test equipment can perform the Stress Paths rock test:- Hydraulic Load Frames for Rock for stress paths rock test 1000kN (1MN) / 2000kN (2MN) Static Compression Only Loadframe for stress paths rock test Environmental Triaxial Testing System for stress paths rock test Environmental Triaxial Automated System for stress paths rock test GDS Small-Strain Hollow Cylinder Apparatus for stress paths rock test GDS True Triaxial Apparatus for stress paths rock test GDS Large Diameter Cyclic Triaxial Testing System for stress paths rock test Hydraulic Load Frames for Soil for stress paths rock test Virtual Infinite Stiffness Load Frames for stress paths rock test Advanced Dynamic Triaxial Testing System for stress paths rock test GDS Enterprise Level Dynamic Triaxial Testing System for stress paths rock test Triaxial Automated System (Load Frame type) for stress paths rock test Triaxial Testing System (Automated Stress Path type) for stress paths rock test
