Constant Rate of Strain Consolidation (GDSCRS)
 
What is it?
 
The GDS Constant Rate of Strain Cell (CRS) is a load frame based one dimensional consolidation cell capable of applying back pressure and measuring pore pressures up to 1MPa (low pressure version) or 20MPa (high pressure version). Coupled with GDS controllers and software the system will run the entire test from start to finish through a loading path specified by the user using constant rate of strain loading.

System Overview
 
Instead of applying stress increments in stages as in a typical oedometer consolidation test the load can be gradually applied to the sample by increasing the axial displacement at a constant rate. Controlled back pressure (water) is applied to the sample and drainage is allowed through the base of the apparatus. The advantage of this method is that the time required to complete a consolidation test can be reduced significantly.
