Shear Overview


csShear

The Clisp Studio csShear module is an add-on to the core package (csHost) that makes it easy for the User to set-up, control and monitor both Direct and Residual Shear Testing in soil testing laboratories, and collate and output the results in industry standard or User defined formats

Shear Test Setup

Clisp Studio csShear comes with the easiest test creation and setup of any Geotechnical Shear software package available today. Choose between Direct or Residual test type, select the appropriate Standard and proceed through the steps of the wizard, initially setting up the specimen details and hardware relevant to your Test set up.




Shear Test Definition

Initial Test Setup

Once the Test equipment has been set up, csShear enables you to create the required Direct Shear test (to BS1377-7, ASTM D3080-04, AS1289.6.2.2 or Q181C) or Residual Shear test (to BS1377-7 or AS1289.6.2.2) for up to 4 samples.

The relevant Shear Instrument and its associated Load and Displacement Transducers can then be selected from the Hardware Setup screen


Specimen Details Setup

The Dimensions setup screen will automatically calculate and display the Specimen’s Area, Volume and Bulk Density from the data entered by the User. Similarly, the Moisture setup screen will automatically calculate and display the Specimen’s Moisture, Dry Density, Voids Ratio and Degree of Saturation from the entered data.


Shear Test Setup

Configure



Shear Test Configuration

With Clisp Studio you have complete control of Shear Testing for both Consolidation and Shearing. Every aspect of each stage can be configured to perform a standards based test or a a custom test specific to your exact needs. 





Shear Test Consolidation

Consolidation Stage Setup

Data logging can be initiated upon a specified Load or Displacement change and the required data can be logged at a prescribed time interval, from a predefined table or on a specific Settlement change.

You can specify the Consolidation stage to be stopped when the Settlement changes by less than a specified amount within a selected time period and/or a specified maximum time is exceeded


Shear Stage Setup

Data logging is triggered when the Load changes at an input rate and can be carried out either at a specified rate, when horizontal strain changes by a particular percentage or horizontal displacement changes by a specified amount. Shear and Reverse speeds can be input manually or calculated automatically andmultiple Shear stages can be set up for Residual Shear tests.

The Shear stage can be terminated when the calculated Shear stress has changed by a given amount within a specified time and/or when the horizontal strain changes by an input percentage

Shear Test Execution

You are able to monitor the status and condition of the Shear test as it proceeds. Live Views, Graphs and Tables show Shear test progress while summary windows give Instrument, test and sample status at a glance. 


Shear Test Live Views

Live Test Views

For both Consolidation and Shear stages, we offer predefined live data views to observe the most commonly measured variables (such as vertical and Horizontal Load and Displacement) and calculated data (such as Displacement, Stress, Strain, Voids Ratio, t100 value etc.) for the specimen being tested, while the Test Stage is running. The User can also customize the desired Live Data from the list of variables that are relevant to that particular stage.



Live Graphical and Table Views

Predefined graphs and tables are available for you to view both the Consolidation and Shear stages as they progress. The Consolidation graph plots Time vs. Vertical Displacement and for the Shear stage both Shear Strain and Normal Stress graphs are available. The tables for both stages display the most commonly measured parameters and expected results at the specified logging intervals.

Report



Shear Test Results and Reports

As well as the completed Live Data View, Graphs and Table, csShear gives you a Summary Graph and a number of reports covering the Consolidation and Shear stages.










csSHEAR Summary report

Consolidation Results

The Consolidation Results provide you with the Vertical Displacement change, the t100 value, the Voids Ratio and the Normal Stress.

Shear Results

The Shear Results give the Vertical and Horizontal Displacement change, Shear Stress, Normal Stress, Volumetric Strain, Accumulative Strain, the Peak Shear Stress (and Displacement at which this occurred) and the Voids Ratio.

There are three predefined graphs as follows:

  • Shear Strain : Horizontal Displacement vs. Shear Stress
  • Normal Stress : Time vs. Normal Stress
  • Shear Summary (Strength Envelope) : Normal Stress vs. Shear Stress

Data Export and Import

Clisp Studio has the ability to export the entire Test to MS Excel for further data manipulation . The Test can also be exported to a script file which can be imported when creating a new Test if desired. This enables Tests from the current or older versions of Clisp Studio to be cloned or even rerun if required.This facility is extremely useful for Test exchange between laboratories or investigation of an issue by VJ Tech.

Reports

As well as the overall summary report, csShear provides the following reports:

  • Consolidation: Time vs, Vertical Displacement
  • Shear Stress vs. Strain
  • Shear Strength Envelope
  • Shear Stress Data
