Rock Mechanics System

Rock Mechanics System



Our Integrated Rock Mechanics System is built to meet your research facility standards. Our system is a completely automated testing apparatus capable of performing the following tests:


  • Unconfined Compression
  • Triaxial
  • Bending
  • Indirect
  • Fracture
  • Post – Failure Behavior
  • Creep
  • Nearly any other compaction test under various stress paths



This complete system consists of:


  • Integrated safety shutdown mechanisms
  • Servo controlled stiff frame to minimum energy stored during test and report accurate modulus and strain values. Axial loads up to 200,000 lbs
  • Pressure vessel 20,000 psi
  • Pressure Generators (axial, confining and pore pressure pumps)
  • Electrical feed through connectors for axial, circumferential deformation, load measurement devices or other special transducers such as acoustics measurements
  • Accepts sample diameters up to 4” with a length of 2 times the diameter
  • In-vessel instrumentation
  • Axial, radial strains boundary condition
  • Internal differential axial stress
  • Hydrostatic confining pressure
  • Compressional (P) , 2 orthogonal Shear (S1,S2), and 45° Acoustic Transducers Propagate @1Mhz
  • Pore pressure and flow rates for vertical & Horizontal SS Permeability determination
  • Temperature up to 450°C
  • A rackmount control system housing:
  • Digital displays
  • Custom-built PC
  • Measurement Instrumentation
  • Acoustic electronics and oscilloscope
  • Open software architecture to servo of any measured or calculated variable. This provides any stress path loading (Triax, Uniax, IsoStatic)
  • Real time data acquisition, process control software, graphical user interface analysis tools
