Exponent Connect – our fully featured software offers sophistication and flexibility
The software of choice for the professional or advanced materials characterisation expert, users requiring long-term flexibility of operation and analysis and those users requiring additionally synchronised data measurement alongside their traditional materials testing data.
Exponent Connect software will maintain its ongoing expansion of testing procedures, presentation formats, data analysis features and enhanced security options. The aim is to provide the most powerful and flexible testing analysis solution available, which is of particular importance for those in Research and Development.
Exponent Connect Lite – straight-forward testing without the complexity
Suited to simple testing offering flexibility and ease of use. Users at all levels will appreciate the minimum learning and training required. This package still provides all of the capabilities you need to run tests quickly and efficiently to achieve maximum productivity.
Upgrading to Exponent Connect is possible at a later date if required.
The following presents a few highlights of the software which can only be fully appreciated by a live demonstration.
Calibration and Force Verification
Making measurements with any analytical method or instrument requires calibration to ensure the accuracy of the measurement. Exponent Connect and Exponent Connect Lite provide for the calibration of Force, Height and Stiffness and Force Verification – simple procedures which take only a few minutes.
Calibration of both force and distance is carried out in-house at the end of the manufacturing process. Customers can easily re-calibrate the instrument in their laboratories depending upon their good laboratory practice.
The accuracy of all of our instruments can easily be checked in terms of speed, distance and force measurements to meet the more demanding regulations of certain industries.
Test Setup and Design
Testing starts with your choice of settings. This will depend on the type of test you wish to perform and the properties which you wish to investigate. There are several options for specifying the way in which the instrument is to test a sample.
Automatically Loading a Test Project
The Samples directory contains an ever-increasing range of over 180 projects from which users can select as a test starting point. At the click of your mouse your chosen sample project can automatically transfer the required test settings to the instrument and load the associated macro, spreadsheet and report ready to analyse and display the results once the test is performed.
Choose a Standard Method or Test Settings and analysis Macro routines can be optimised to suit your particular applications and if routinely required they can then be saved as user-specific Projects. A Project combines all of the components required to initiate a complete test and analysis procedure and is the basis on which a user can centralise all files required for a specific product test.
Alternatively, it is very easy for you to write your own method for the particular analysis required.
Choosing from a Test Library
A series of classical mechanical tests are included from which simple or 'enhanced' versions are available for selection. A TA Settings window is displayed which allows the user to specify such parameters as speed and test distance required for the test procedure. Advanced features within a test can be hidden for simplification. All TA Settings parameters have a caption which explains what each parameter does. Define your own test project and roll it out across multiple locations with multiple users to ensure consistency and accuracy in testing.
Running Tests and Collecting Data
Before testing, a Run a Test window establishes test options and post-test parameters (e.g. file name, batch name probe used, etc.) Sample dimensions can also be specified for further analysis.
Data can be captured at high speed (up to 2000 points per second) which is a particularly important aspect when testing products that fracture (e.g. tablets, biscuits) or require high speed separation such as during the testing of adhesives.
The ability to plug-in additional measurement instruments is present in the instrument design to provide multi-channel data acquisition. This allows for many other measuring devices to be connected and their data simultaneously collected, such as acoustic emission, temperature, humidity via Exponent Connect software.
During testing of your sample, force, distance and time values (and additional peripheral data values if attached) are collected and the real-time data displayed in a Graph window.
The Graph can be annotated to highlight the areas of interest and its axes can be changed to display the data in different X and Y combinations. Logarithmic and second Y axes are also available to allow synchronous display of additionally collected data such as temperature.
Graph files can include photos of the sample tested, and can also be exported as .bmp or .jpg.
Once data has been collected and is displayed in a Graph window, there is likely to be a requirement to analyse it in order to interpret the results and draw conclusions. Exponent Connect provides a wealth of analytical tools, from the most basic option of collecting a single force value to more sophisticated methods of curve smoothing or detection of inflection points.
Almost any feature of a data characteristic can be recognised and recorded. Icons for the calculations of such parameters as Area, Gradient, Time Difference, Mean, Count Force peaks, Force Maxima/Minima etc. are quickly accessible on the toolbar or minimised to only those required by the user via the Customisable Toolbar option. Quick Calculation Macros are a selection of popular calculations that you can choose from that will analyse the data to provide results in just a few steps.
A Macro simplifies repetitive analysis and display. A set of instructions are listed and executed which automatically collect data from the graph. Tests can be automated with either intricate or simple macros, the latter being ideally suited to a production environment.
Engineering macros are built in for you to choose from depending on the performed test.
At the end of each test, an operator need only concentrate on the positioning of their sample and starting their next test whilst the previous data is analysed in the background.
Exponent Connect not only provides an extensive library of macros that are ready to quickly analyse your materials testing data once your tests have been performed, but enables the writing of macros that can quantify almost any aspect of the data resulting from the test. The flexibility to perform such a wide range of sophisticated additional mathematical functions within the software is unrivalled.
Regardless of whether the test is performed in compression or tension, a resulting curve can be analysed to obtain the following typical parameters:
• Strain rate
• Young’s Modulus
• Tangent, chord and secant modulus
• Yield stress
• Strain to yield
• x% proof stress
• Maximum stress
• Strain at maximum stress
• Energy to maximum stress
• Breaking strain
• Hysteresis %
• Energy to failure
When specifically measuring in tension additional parameters may include:
• Necking onset
• Ultimate tensile strength
• Strain hardening parameter
• Strength coefficient
Flexure using three point bend for cuboid and cylindrical samples:
• Yield stress
• Young’s Modulus
• Flexural strength
Indentation using conical and spherical probes:
• Indentation modulus
• Elastic energy
• Plastic energy
• Indentation energy
Puncture of uniform thickness thin films using spherical probes:
• Failure Strain
Exponent Connect software is extremely well suited to the analysis of materials test data. Custom graph axes may be plotted to display a wide range of functions, such as stress and strain for any standard test geometry, true stress and true strain, and many other variations.
Graphs can be automatically manipulated and analysed to, for example, find 1st, 2nd and 3rd derivatives, locate breaking points and perform calculations using variables such as graph values, sample information and test settings.
The analysed data is displayed in a Results window in customised spreadsheet format and if necessary extra calculations are made by the addition of more columns to further manipulate your data or produce other parameters using either your own or stored formulae e.g. Standard Deviation, Average etc. Multiple worksheets are available to separate product parameters from results and user data.
Spreadsheets, text or images can be exported to other Windows applications for further specific manipulation/presentation if required. Once your range of tests are performed the collection of parameters you have obtained can be collated into a 'fingerprint' of each sample.
Presentation and Layout Options: Exponent Connect only
Once data is collected in a spreadsheet, charts in a multitude of formats can be automatically displayed or designed to suit your data comparison needs.
A Chart gives a visual representation of the data from the Results window to allow easier comparison and interpretation. The Chart Designer allows selection of chart type and defines position, legend styles, base and wall styles and axes types.
A Report is a great way to establish a strict format for presenting information for others. For example, reports allow users to present hourly online test results to their managers or to present well-formatted reports to marketing and customers.
Reports may include graphs, results files, charts, pictures, logos, text, test settings, test preferences, batch numbers, information about the products tested, etc.
A Report can be a user formatted composed presentation of the complete analysis using the WYSIWYG word processor type interface. Alternatively reports can be automatically generated from active objects and fields when a report template is open which can be set-up to print, save or email when tests are complete. A Spell Checker, Thesaurus, adjustable fonts and styles and support for tables, OLE objects and export to HTML are also included.
