XJTUDIC---Displaying and Editing Results

The result representations of strain can be visualized as Technical, Logarithm or according to Green. You can choose which one to display by setting the parameters.

The displacement and strain of each deformation state can be displayed by the form of points, grids and curved surfaces. Moreover, XJTUDIC can display the strain isogram, strain direction, and local coordinate system.

1.1      Sections

With the menu Sections£¬you can create two kinds of sections. As shown in Figure 5-3, 5-5.

1.1.1   Plane Sections

With Sections->Plane Sections, you can create a plane section according to the pop-up dialog window.

1.1.2   Circular Sections

With Sections->Circular Sections, you can create a circular section.

1.2      Filtering

You may filter result data in order, for example, to suppress possible noise or to emphasize local effects. The filter function may be used for selected stages or for all stages and additionally for selected areas or for not selected areas.

 

Example for filtering:

3D view prior to filtering

3D view after  to filtering

No filter function will change the coordinates of the 3D points. Function Filter only influences the result data.

Parameter:

Brief Description:

Filter type

Average

The statistic average is calculated.

Median

The central value is calculated (the values are sorted by size and the value in the middle is used).

Runs

Number of runs for the adjusted filter parameters. If the value is 0, no filtering is performed.

Size

Number of grid points for filter computation, e.g. 3 means that the center point of a 3x3 grid is filtered. The filter function is based on the adjacent grid points.

Filter quote

Input of the validity quota of grid points in %. If, for example, Size 3 and Filter quote 50% is adjusted, at least 50% of the grid points must be present in the 3x3 grid in order to be filtered.

1.3      Interpolating 3D Points

If your result representation has holes because, for example, the spray pattern failed at a point, you may fill these holes by means of interpolation.

In the interpolation parameters, Maximum size means the maximum size of the hole to be filled, Calculation range means which states will be interpolated.

1.4      Legend Settings in the 3D View

Optimizing the legend can make the 3D view display better, and will be good for observing and analyzing.

1.4.1   Fixed Legends with Manual Maximum and Minimum

Start the Evaluation Mode using the respective icon in the tool bar, with Control ->Parameters setting; you can adjust the threshold of the legend to optimize the 3D view display.

 

Figure 510

1.4.2   Optimizing the 3D View Display

For the same deformation state, if the strain value or other data is too small and the legend limits are scaled automatically based on the largest and smallest measuring value, then the very big measuring noise of the system is displayed in the 3D view.

1.5      Stage Points, Info Points

Info Points are individually definable points in the 3D view of the specimen. The info point is used for getting fast and temporary information. Clicking with Ctrl and left mouse button in the 2D camera image or in the 3D view creates and Info Point. Info Points may be defined on the surface of the specimen (facet center points) or on sections.

1.6      Point Pair

Point pair is used for tracing the distance between two points on the specimen surface through the deformation process.

With the menu ¡°Point Pair¡± or with right mouse button clicking on the tab Point Pair, you can create and edit the point pair. As shown in Figure 5-13.

1.7      Image Series

With the menu ¡°Image Series¡± or the respective tab, you can create, display and edit the image series.

1.7.3   Edit, Import, Export and Delete Image Series

You may edit, import, export and delete the image series as required.

1.8      3-2-1 Transformation

The location of the coordinate system is determined by the calibration results. But in the actual measurement, in order to evaluate the results more easily, the coordinate system needs to be transformed. 3-2-1 Transformation is one of the mostly used methods.
