Load the Test Data

Load the test data in the 3DEXPERIENCE platform.

Before you begin: Download the test data from the Dassault Systèmes Knowledge Base article, Sample Data: Johnson-Cook Material Calibration of Aluminum.
  1. Open a native client on the 3DEXPERIENCE platform.

    The technique that you use to open a native client depends on your installation and environment. For example, you can open a client from a desktop shortcut or from an email invitation to a 3DDashboard.

    For more information, see the Getting Started guide.

  2. From the Compass, click Material Calibration.
    The app opens and displays the Calibration Setup panel. This panel provides access to most of the actions you need to complete a calibration: loading the test data, selecting a material model, plotting test data and material response, and adjusting parameters before running a calibration.
  3. From the top of the Calibration Setup panel, click Test Data .
  4. From the file selection dialog box that appears, navigate to the test data for A356 aluminum (EXAMPLE-Aluminum-TestData.txt), and click OK.
    The Material Test Data Import dialog box appears with your data displayed in a table.
  5. Name the material test data Uniaxial.
  6. From the Domain options, select Time.

    You can import either time- or frequency-based test data. The test data for this example is in the time domain.

  7. From the Deformation mode options, select Uniaxial.
  8. From the Delimiters section, select Tab only.



    You select tabs because the data points in EXAMPLE-Aluminum-TestData.txt are delimited with tabs.

  9. Start the import of material test data at row 2.

    Starting the import process with the second row skips the header information in the first row.

  10. Click Next.
    The Material Test Data Import dialog box displays the imported data in an X-Y plot and in tabular format.

    You can modify the header of the data table to relabel the type of test data in each column.

  11. Relabel Column 1 as the Nominal Uniaxial Strain (%), and relabel Column 2 as the Nominal Uniaxial Stress (MPa).
  12. From the X-Axis options, select Nominal Uniaxial Stress (MPa); and from the Y-Axis options, select Nominal Uniaxial Strain (%).


  13. Click Finish.
    The app opens the Plot panel and plots the test data points in red.

    In the Calibration Setup panel, the imported test data (Uniaxial.1) appears in the Test Data Sets section; and the plot of the test data (Plot.1) appears in the Plots section.
