MITTA AB Invest in New Stress Path Apparatus for Testing Soft Clay

Alexis Antoniou a Geotechnical Systems Engineer from GDS Instruments has recently returned from Sweden, where he installed three Bishop and Wesley automated triaxial testing systems. MITTA AB are developing their temperature-controlled laboratory in Gottsärk to expand their abilities to test soft clays.

GDS was honoured this month to receive a visit from Laurie Wesley

GDS was honoured this month to receive a visit from Laurie Wesley, world renowned soil mechanic, PhD Student of Professor Alan Bishop, and inventor of the famous triaxial cell that takes his name the “Bishop and Wesley Stress Path Cell”. Laurie, from Auckland New Zealand, designed the cell during his PhD with Alan Bishop in the mid 1970’s.  GDS have been producing a stress path triaxial cell based on Laurie’s design since the early 1980’s, and still produce and updated version of this extremely flexible triaxial cell now.

Case Study: Temperature Controlled Stress Path Testing

The stress path test is commonly used to simulate the changing mechanical properties of soils, whilst under varying stresses. Research in this area, within China and abroad has gradually increased. The static triaxial apparatus based on the Bishop Wesley principle is widely accepted. However, in reality, the stress change of soil is usually accompanied by changes in the environment.
