Hollow Cylinder Testing

  • The anisotropy of soil samples,
  • The effects of principal stress rotation,
  • The effects of intermediate principal stress. 

Two versions of the system are available, a dynamic and a lower cost "static" version.  GDS HCA has been built specifically for very accurate long-term work with the capability for a level of dynamic performance. There has been excellent work carried out using GDS systems at LNEC, Portugal, University of Southampton, UK, amongst others. In addition there is a paper in Ground Engineering where the researchers have chosen to use the GDS approach along with a number of GDS components.
