Cyclic / Stress Path Triaxial System

The Wikeham Farrance feedback controlled cyclic triaxial system applies cyclic or dynamic loading to the soil specimen.
The system is a digitally controlled, servo pneumatic (closed loop) system, which controls three parameters: axial stress, confining pressure and back pressure.
The base system incorporates an integrated Multi-Axis Control System (IMACS), a digitally controlled 5 kN actuator, Tritech 50 or Tritech 100 load frame, auxiliary air receiver complete with two servo valves for cell and back pressure control, two air filters and associated cables. The system is supplied complete with cyclic and stress path software.
A double acting digitally controlled pneumatic actuator applies axial load.
This cyclic load can be applied in load (N), stress (kPa), displacement (mm) or strain (%).
Digitally controlled pneumatic valves apply confining and back pressures.
The dynamic tests are generally carried out in conjunction with static imposed conditions of stress to the soil samples.
The WF Static and Dynamic Cyclic Triaxial system has been designed to perform the following tests:
• Standard triaxial tests (UU, CU, CD) including saturation, isotropic and anisotropic consolidation with pore pressure and volume change measurements
