All Clisp Studio Modules follow a single principal design philosophy. All tests have an Assistant that directs the user from test setup to results analysis and export.

Choose your hardware and set up the sample details. Set your test conditions and then initiate the test. You can now leave the test running and perform other duties, knowing that you will return to a completed test with results you can deliver to clients or research bodies with confidence.


Due to the industrial strength of Microsoft SQL Database back end, your data is safe, and secure and can be backed up with standard Microsoft backup technologies to be stored offsite.

Your application and test data are safe. Through a combination of a Hardware Security Dongle and Microsoft Windows User Controls, unauthorised personnel will be unable to gain access to your tests or make unapproved changes to the data contained within them.

We support every system with exceptional operational support, from the single researcher to the largest organisation.

System Alarms and Warnings

Clisp Studio has many levels to check for errors, ensuring the highest of protection for the User’s data. It also features numerous alarms and warnings to indicate any problems when commencing, running, or analyzing tests.

There are three indicator lights permanently displayed on the main toolbar – ‘Threads’, ‘Comms’, and ‘Alarm’, and a ‘Stop’ option to halt a test prematurely if required. If any indicator starts to flash, hovering the mouse pointer over the indicator will provide information as to the cause of the problem and a possible solution.

  • The ‘Threads’ light will flash if Clisp Studio detects that the System is becoming overloaded.
  • The ‘Comms’ light will flash if communication is lost with one or more Instruments.
  • The ‘Alarm’ indicator will flash when a software error has occurred.

If the User’s data becomes compromised or damage to the instrument occurs, Clisp Studio will halt the test.


Every Clisp Studio module is designed to be able to run in a fully automatic fashion*. Instrument and accessory automation allow a test to be started and run independently, requiring no further user interaction until the results are verified and printed.

  • Email notifications inform you when tests have been completed allowing you to walk away and only return when notified that you need to prepare for the next test or stage.
  • Multiple Station Control allows you to run a series of tests simultaneously on numerous stations with or without human intervention. For instance, you might have multiple Cells and only one Load Frame and thus require notification that the Consolidation of a sample is finished and that it is ready to be placed in the Load Frame for Shearing. At the same time another sample may have finished Shearing and the cell will be available for another use. This sort of setup enables commercial laboratories to operate production line-like testing continuously and not have to waste precious chargeable time.
  • The automation features of Clisp Studio have been developed over the course of many years, through rigorous testing and feedback. We are constantly adding ways to support the working practices of every customer we have and will continue to do so for the lifetime of the product.

 * Some tests require optional accessories to operate in fully automatic mode.


Clisp Studio has many safety features built in to protect the user, the sample, and the instruments being used from damage or inappropriate usage.

Here are a few examples.

  • Sensory overload prevention due to incorrect test conditions. (i.e., requesting a 5 kN load when you only have a 2.5 kN load cell).
  • Displacement sensors are protected in the event of unexpected sample collapse.
  • The User is warned if they select hardware for a new test that is currently in use on another station.
  • The test will be suspended on the loss of communications (i.e., a cable has inadvertently been pulled out or an instrument switched off).
  • If a test has been started with existing data, the User is warned that continuing will overwrite the existing results, offering the choice to add further data or overwrite the existing data.
  • The User is warned if an instrument to be used in a test is not communicating correctly, before starting the test.
  • If the test is being run on a low-specification PC, the User is informed when unacceptable performance levels are reached due to running too many simultaneous tests.

    and many more such examples of real-world scenarios that require caution, protection, and best practice assistance.


Clisp Studio is designed to be modular allowing test modules to be purchased and added when required. When a new Instrument is purchased, the Clisp Studio (cs) Module that goes with it can be purchased using our instant module delivery system and testing can begin immediately.

Clisp Studio in its basic form (without purchasing any modules), will allow data collection from all instruments and plot data in graph, table, or instant view formats. It does not allow automatic control of instrumentation, that’s where the csHostAdvanced module comes in. Clisp Studio’s true power lies in the customisation permitted by this Advanced module as it allows you to create 100% personalised test procedures with instrument control, data collection, and calculation, test triggers to start and stop instruments, and results manipulation and presentation. Clisp Studio offers a truly open and flexible solution to Fully Automatic Geotechnical Testing.


Standards: We have spent years ensuring the Clisp Studio Modules continue to conform to International Standards Bodies. As such, each Module supports one or more appropriate standards from the United Kingdom, United States, and Australia.

Great care is taken to ensure that not only is the standard testing procedure followed but also the real-world operational practices of laboratories.

Languages: Clisp Studio now supports several different languages in all modules.

The text has been improved by local Geotechnical engineers to best match both the Geotechnical correctness of terminology and current best practices within each region.


Although Clisp Studio provides commonly used templates, the User can customise many aspects of testing as required. The following list illustrates some of the possibilities.

  • Customisation of Live Data Views to show variables of interest to the User.
  • Customise result graphs, plotting desired variables on the x and y axes.
  • Customise result tables with as many results as required.
  • View measured inputs, instrument states, test status, comms details, and event logs as required.
  • Switch between imperial and metric systems and tailor individual quantities (i.e., Force, Mass, Length, etc.).
  • Set up User and Client-specific details for test and report data.
  • Detail Test Engineer and times of testing for traceability.
  • Set up e-mail details for test notification.
  • Configure audio files.
  • Passcode authorisation control.

Available Modules

csBENDThe Bender Software module enables the User to the small strain shear modulus (GMax) of soft and stiff clays using a non-destructive testing method. The software is used with the VJ Tech Bender Scope and uses a set of one transmitter and one receiver element, fitted on a top cap and a base pedestal, respectively.

csBender incorporates filtering options to refine the raw data and stucking options to combine data from several waveforms. Different types of waveforms are supported, including sinusoidal, triangular and square waves.
csCBRThe CBR Software module enables the user to determine the California Bearing Ratio (CBR) of pavement subgrade, subbase, and base course materials from laboratory compacted specimens.

The software includes automation options to minimise human involvement and several live views, graphs, and data tables which allow for quick and simple determination of the CBR value. The software is used with the VJ Tech Standard and Advanced load frames.
csCONSHEARThe Constant Shear Software module enables users to perform Direct and Simple shear tests, tailored to the user’s specific requirements. It includes the ability to perform multiple consolidation stages at increasing or decreasing vertical stress combinations. Shear stages can be performed using Constant Normal Stress, Constant Normal Height, or Constant Normal Stiffness boundary conditions.

The tests can be fully automated to minimise human involvement. csConstantShear is used with the VJ Tech Shearscan Pro and VJ Tech Shearscan Pro SS load frames.
csHOSTThe csHOST Software module enables the users to log raw data from any sensor connected to a VJ Tech data logger. The user can create custom-made initial and stopping conditions which can provide the required data during a manual test. csHost module can be used with any VJ Tech data logger.
csHOSTADVThe csHOSTADV Software module provides all the features of the csHOST software module plus additional features that can be used to create specific tests tailored to the user’s requirements. These features include the creation of additional schedules & stages, the definition of simple and advanced variables from the collected raw data, and several tools to plot the raw and processed data.

In addition, csHostAdvanced provides the ability to automate the tests and create advanced control options for the VJ Tech frames and controllers.
csDYNADSS-CThe Dynamic Simple Shear with Confining Pressure Software module enables the user to perform cyclic simple shear tests on samples contained within a triaxial-type cell and pressurised under Confining Pressure. The module introduces the ability to saturate the specimen under a controlled Back pressure, similar to triaxial testing. Multiple options for sample consolidation include isotropic, anisotropic, and Ko consolidation. Moreover, the specimen can be subjected to Monotonic and/or Cyclic loading under various Normal boundary conditions (Constant Normal Stress and Constant Normal Height).

A specially designed stage for the study of the liquefaction potential of a soil specimen includes cyclic loading, followed by the restoration of the pore pressure and effective vertical and horizontal stresses before it is subjected to monotonic loading to determine the shear strength properties. csDYNADSS-C module is used with the VJ Tech Dynamic Simple Shear with Confining Pressure (DSS-C) testing system.
csDYNADSSThe Dynamic Simple Shear Software module enables the User to apply the testing procedures for the measurement of cyclic strength, number of cycles to liquefaction, or cyclic properties (Modulus and Damping) of soils, after one-dimensional consolidation, using a cyclic mode of loading.

The module offers the ability to automate the testing procedure with minimum human involvement. One-dimensional consolidation can be performed in loading steps while monotonic and cyclic shear stages can be performed on either drained or undrained conditions. The csDYNADSS module is used with the VJ Tech Dynamic Simple Shear (DSS) testing system.
csDYNAThe Dynamic Triaxial Software module enables the user to determine the cyclic strength (also called the liquefaction potential) of saturated soils in either intact or reconstituted states by the load- or displacement-controlled cyclic triaxial technique. The sample is saturated using the same techniques that are used in static triaxial tests, involving incremental Back pressure. Isotropic, anisotropic, and K0 consolidation options are available, while the specimen can be subjected to several stress paths in a q-p or s-t environment.

Cyclic loading can be performed either in load or displacement control while either drained or undrained conditions can be applied. csDYNA module can be used with the VJ Tech Dynamic Triaxial system.
csHCTThe Hollow cylinder test involves four different applied stresses to the sample, Axial, Torsional, Inner, and Outer confining stresses. This gives four degrees of freedom to the deformation of the specimen. The sample is in the form of a thick hollow cylinder fixed between two rigid platens.

The hollow cylinder test aims to study the behaviour of the application of three unequal principal stresses to the specimen and the impact of the stresses from rotation when the specimen is rotated.
csMARSThe Marshall Software module enables the User to perform Marshall Tests to determine the properties of a finished asphalt concrete surfacing structure mix to be used for the construction of roads or pavements. The software is used with the VJ Tech TriSCAN Advanced frame (which has built-in data logging).

csPERMThe Permeability Software module enables the User to perform a permeability test using either a Rowe Cell or Triaxial Cell setup to determine the rate of water flow through a sample.
csRESThe Resilient Software module enables the User to perform resilient modulus tests on Subgrade or Base/SubBase samples in a laboratory. The test software simulates the physical conditions and stress states of materials beneath flexible surfaces subjected to dynamic loading (i.e. moving wheel loads). The sample may be sheared following the Resilient Modulus test if required.
csRINGThe Ring Shear Software module enables the User to perform tests to determine the residual shear strength of cohesive soils, which is particularly important when assessing slope stability.
csROWEThe Rowe Software module enables the User to perform a Rowe Cell consolidation test to determine the magnitude and rate of consolidation of a sample using hydraulic vertical load.
csSDSWCCVJ Tech’s csSDSWCC Software is used to determine the SWCC at different ko stress conditions, trying to replicate the stress state occurring at deeper soil layers. The Test is for a 70 mm diameter specimen with suction being generated using a Pneumatic APC at the top of the sample and a Hydraulic APC at the base, thus applying the axis-translation technique. Both drying and wetting SWCCs can be determined, allowing hysteresis to be studied.
