Home Test Methods Rock Testing Stepped Loading Rock Test Equipment Stepped Loading Rock Test Equipment Stepped Loading provides a means to increase the specimen axial load, whilst maintaining a constant back pressure and measuring the back (pore) volume change. Please note: Some apparatus may require additional components or software modules to perform certain tests. The following rock test equipment can perform the Stepped Loading rock test:- Unsaturated Back Pressured Shear Box for stepped loading rock test Hydraulic Load Frames for Rock for stepped loading rock test 1000kN (1MN) / 2000kN (2MN) Static Compression Only Loadframe for stepped loading rock test GDS Large Automated Direct Shear System (300mm) for stepped loading rock test GDS Constant Rate of Strain Cell (CRS in Load Frame type) for stepped loading rock test GDS Consolidation Testing System (Rowe and Barden Type) for stepped loading rock test GDS Shearbase System for stepped loading rock test GDS Electro-Mechanical Dynamic Cyclic Simple Shear for stepped loading rock test Environmental Triaxial Testing System for stepped loading rock test Variable Direction Dynamic Cyclic Simple Shear for stepped loading rock test Dynamic Back Pressure Shearbox for stepped loading rock test Back Pressure Shearbox - High Pressure for stepped loading rock test Interface Shear Tester for stepped loading rock test Environmental Triaxial Automated System for stepped loading rock test GDS Small-Strain Hollow Cylinder Apparatus for stepped loading rock test GDS Back Pressured Shear Box for stepped loading rock test GDS True Triaxial Apparatus for stepped loading rock test GDS Large Diameter Cyclic Triaxial Testing System for stepped loading rock test Advanced Dynamic Triaxial Testing System for stepped loading rock test GDS Enterprise Level Dynamic Triaxial Testing System for stepped loading rock test Hydraulic Load Frames for Soil for stepped loading rock test Virtual Infinite Stiffness Load Frames for stepped loading rock test Triaxial Automated System (Load Frame type) for stepped loading rock test Triaxial Testing System (Automated Stress Path type) for stepped loading rock test GDS Automatic Oedometer System for stepped loading rock test
