GGU-DIRECTSHEAR: Measured data input via ASCII data import

For a test employing a shear stress-path diagram the measured data are imported from an ASCII format file. The following dialog box will open, for example.

The normal stress selected for an individual test is entered in the first row in the dialog box. Four further data points can be entered below this, but are irrelevant for test evaluation and only serve to describe the course of the test. Editing of the texts, or hiding them completely, such as the boxes for water content in the dialog box above, is possible via the menu item "Output preferences/Texts", "Test texts" button (see Section 5.4.2). The colour and width of the pen used for the individual test can be user-defined.

The program automatically determines the failure value (maximum value of all measurements in a test) and the slip value (last value of all measurements in a test) from the shear stress-path diagram. If it is anticipated that test evaluation requires further data, activate the "Shear path (failure) [mm] individually" check box and enter the shear path at which it is estimated failure occurred. In analogy, corresponding input can be selected for the slip value.

The following additional actions can be performed:

• "Edit data"
  All measured data are displayed in a dialog and can be edited. New measured data can be entered by hand after clicking the "Edit no. of values" button by increasing the number as required, or by decreasing if data at the end of the list is to be deleted.

Under certain circumstances when importing the measured data from the shear apparatus, there may be so many data points that it takes a long time to build up the visualisation of the path diagrams on the screen. The number of measured data points can be reduced to the required value via the "Reduce measured data" button. The measured data cannot be restored following this action!

Under certain circumstances when importing the measured data from the shear apparatus, there may be so many data points that it takes a long time to build up the visualisation of the path diagrams on the screen. The number of measured data points can be reduced to the required value via the "Reduce measured data" button. The measured data cannot be restored following this action.

Using the "Modify" button all measured data can be increased or reduced by applying a constant.

• "Delete test"
  The currently displayed test will be deleted.

• "Duplicate test"
  The currently displayed test will be duplicated. You will automatically find yourself in the next test.

• "Import ASCII file"
  The measured data can be imported from a file in standard ASCII format. In addition, ASCII data in the file formats of the shear apparatus manufacturers Wille Geotechnik, Micronic and Straßentest can be imported.

• "Show data"
  Result data for the current test will be calculated and displayed in a dialog box.

• "Done"
  You will arrive back at the previous dialog box. All values entered will be accepted.
