Home Test Methods Rock Testing Axial or Radial Deformation Rock Test Equipment Axial or Radial Deformation Rock Test Equipment Axial deformation is measured by a displacement transducer in all GDS systems (LVDT, LDT or digital gauge). Radial deformation is calculated as standard by measuring the volume change to 1mm3 directly on the back pressure controller. For direct measurements of radial strain (i.e. transducers mounted upon the sample, and direct measurements of axial strain in the same way, GDS can supply a Hall Effect local strain set or an LVDT local strain set. Please note: Some apparatus may require additional components or software modules to perform certain tests. The following rock test equipment can perform the Axial or Radial Deformation rock test:- Environmental Triaxial Testing System for axial or radial deformation rock test Environmental Triaxial Automated System for axial or radial deformation rock test GDS Small-Strain Hollow Cylinder Apparatus for axial or radial deformation rock test GDS True Triaxial Apparatus for axial or radial deformation rock test GDS Large Diameter Cyclic Triaxial Testing System for axial or radial deformation rock test Advanced Dynamic Triaxial Testing System for axial or radial deformation rock test GDS Enterprise Level Dynamic Triaxial Testing System for axial or radial deformation rock test Hydraulic Load Frames for Soil for axial or radial deformation rock test Virtual Infinite Stiffness Load Frames for axial or radial deformation rock test Triaxial Automated System (Load Frame type) for axial or radial deformation rock test Triaxial Testing System (Automated Stress Path type) for axial or radial deformation rock test GDS LVDT Local Strain Transducers for axial or radial deformation rock test GDS Hall Effect Local Strain Transducers for axial or radial deformation rock test
