An Introduction to Direct Simple Shear (DSS) Testing

Dynamic Triaxial testing is performed on soils when it is necessary to evaluate their strength and deformation properties under cyclic loading conditions. These conditions might include dynamic loading coming from earthquakes, passing vehicles and trains, sea waves, wind, vibration machines etc. There are many variations of Dynamic Triaxial tests and the user should select the one that is most accurately simulating the conditions in the field.

For some testing, system corrections may need to be applied that are not specific to a particular Instrument (e.g. Volume Change due to Cell and tube expansion in an Unsaturated Test). Alternatively, corrections may need to be applied to apparatus used in a Test that is not declared as an Instrument (e.g. frame deformation of an Oedometer). 

Clisp Studio can create a secondary backup of the data captured as a test is running. The secondary backup is a file stored outside of Clisp Studio and can be used to recover data after a computer hardware failure.

PID settings are used in Clisp Studio in conjunction with a DSC2000 to fine tune the performance of a dynamic servo, both single (DSC2000 M) and dual axis (DSC2000 MM and HM). This support document is not designed to give a full accurate account of what PID’s are and how they are calculated.
