Stresses on Surfaces

The result tables of the Stresses on Surfaces category contain the determined stresses with the respective design ratios.

The surface stresses are sorted in the tabs according to the following criteria:

  • Loads (design situations, load combinations)
  • Surface properties (materials, thicknesses)
  • Objects (surfaces, FE mesh points)

Surface No.

For each stress type, the column shows the number of the surface on which the greatest value is available.

Mesh Node No.

The column shows the number of the FE mesh node for which the program has determined the maximum design ratio.

Info

If you have specified the "Calculate results in grid point" option in the Global Settings dialog box if you have set the option 'Calculate stresses on grid point', the numbers of the grid points are shown in this column. The results are then available in the Surface Grid .

Mesh Node Coordinates

The global coordinates X, Y, and Z of the FE mesh nodes are shown in three columns.

Design Situation

This column indicates the number of the Design Situation for which the individual stresses are available.

Loading

This column displays the numbers of the load or result combinations that are governing for the respective stress.

Layer No./side

If you have defined a surface by means of layer elements using the Multilayer Surfaces add-on , the numbers of layers are displayed with the respective stresses.

For the maximum value of each stress type, the program shows the position in the cross-section of the surface or layer on which the stress is occurs: Top, Middle, or Bottom.

Stress type

This column lists the stress types that you have defined and assigned to the Surface Configurations.

Existing/limit stress

For each stress type, the provided stress is indicated with the corresponding limit value.

Tip

Dialog box Surface Configuration dialog box, you can see the equations for each stress according to which the stresses are determined.

Stress ratio η

The final column shows the stress ratios (design ratios) related to the limit value. The utilization degree is expressed by the length of the colored bar.

Filtering stresses by design ratio

The list on the right in the table toolbar allows you to filter the tables by the utilization degree. The Max option displays only the governing maximum stress ratio for each object.

You can also define your own filter options in the format "> #.##" in this list. Thus, only the ratios greater than the user-defined value are displayed in the table.
