FHCA-300 Frozen Dynamic Hollow Cylinder System


The GCTS FHCA-300 Frozen Dynamic Hollow Cylinder System is a highly advanced system that can perform hollow cylinder tests on soil samples at very low temperatures. This system has direct digital serco control of the axial load, torque, temperature, confining pressure, internal pressure, and back pressure. This allows to have accuracy not currently seen by systems on the market. 

 

  • Complete "turn-key" system
  • Closed-loop digital servo control
  • 1000 N-m torsional loads and 100 kN axial loads
  • Testing frequencies up to 50 Hz
  • Temperature control from -30°C to 80°C
  • Confining pressure, back pressure, and internal pressure servo control up to 20 MPa
  • Capable of deflections up to 45°
  • Standards systems test specimen with 100 mm outside diameter and 63.5 mm inside diameter
  • Capable of performing resonant column tests and ultrasonic tests
  • Optional platens for various specimen diameters available

The GCTS FHCA-300 Frozen Dynamic Hollow Cylinder System is capable of performing true triaxial tests on frozen specimens. This system can simulate most field stress/strain path tests (either static or dynamic) including plane strain, simple shear, and small shear strains. This system is also capable of performing other tests, including measurement of dynamic shear strength and deformation, liquefaction potential, shear modulus, and damping ratio, all at controlled temperature conditions. 

  • 100 kN axial load capacity
  • 1000 N-m torsional load capacity
  • 20 MPa confining pressure capacity
  • Temperature control from -30°C to 80°C
  • 45° maximum rotation
