Stress-Strain Analysis

In the Stress-Strain Analysis category of the Navigator – Data and in the table, you can make the basic assignments for the analysis. You can check the objects to be analyzed, their materials, cross-sections, and thicknesses, and assign the analysis configurations to the objects. The input data in tabular form also form the basis for the documentation in the printout report.

Input Tables

The functions known from RFEM are available for working in the input tables. General information can be found in the chapter Tables of the RFEM manual.

Specific tables relating to the add-on are described in the following subchapters:

Use the Global Add-on Settings button in the input tables or the shortcut menu in the navigator entry to open the Global Settings dialog box for the stress-strain analysis.

Configurations

The detailed settings for the stress-strain analysis are managed in the Configurations. There are specific configurations for various object types where you can define limit values or certain calculation specifications for stresses, for example.

Assigning Configuration in Dialog Box for Object Editing

The analysis configurations are designed as types for the individual object types. You can create different types and assign the corresponding configuration to the objects in the Stress-Strain Analysis – Configuration tab of the editing dialog box.

Select an existing configuration in the "Configuration" list or use the New , button to create a new type. The Multiple Selection button allows you to graphically select another object to import its configuration. Use the Edit button to access the editing dialog box of the configuration.

Assigning Objects in Configuration Dialog Box

You can also assign the objects in the configuration dialog boxes.

The "List" on the left in the section of a configuration dialog box contains all configurations available in the model for the specific object type (a member, a surface, a line welded joint, a solid). You can use the New button to create a new configuration with default parameters; the Copy button allows you to copy the selected configuration. You can delete a configuration using the Delete button.

To assign the configuration selected in the list to the objects, enter the object numbers in the "Assigned to…" section above. You can also use the Select Individually button to determine the objects graphically.

Assigning Objects in Configuration Table

In the input tables of the configurations, you can also assign the objects to the configurations.

Important

No stress-strain analysis is carried out for an object with no configuration assigned.
