Materials

The “Materials” table in the “Aluminum Design” category lists all the materials you have created in the model.

Color Emphasis on Materials for Aluminum Design

Allowable Materials

Aluminum Design is linked to the materials of the Aluminum type. The font color of the materials provides information about the use and allowability of the material. The colors mean:

• Black: The material is suitable for the design and is used for the objects to be designed.
• Red: The material is not suitable for the aluminum design.
• Blue: The material is not used in the model.
• Gray: The material is not used for the objects to be designed.

Objects that have been assigned an invalid material are not included in the design, even if the “To Design” option is activated for this material. They are automatically marked as “Not Valid / Deactivated” in the Objects to Design table.

Removing Material from Design

For a valid material, you can exclude all objects with this material assigned from the design by deactivating the “To Design” check box. These objects are then classified as “Not Valid / Deactivated” in the Objects to Design table and are not analyzed during the design.

Adjusting Material Properties for Design

If you want to use user-defined strengths or partial safety factors for Aluminum Design, you can adjust the material properties: Double-click the corresponding table row or use the button in the table toolbar to open the material editing dialog box.

Dialog Box "Edit Material", Adjusting Material Properties

Activate the "User-defined material" option in the "Main" tab. This allows you to edit the material properties. In the "Material Properties" tab, for example, you can change the stiffness of the material and the strengths in the individual thickness ranges.

In the "Aluminum Design" tab, you can adjust the partial safety factors of the material for the design according to the selected [[#/en/downloads-and-information/documents/online-manuals/rfem-6-aluminum-design/000562# image026176 standard], for example, γ_M0 and γ_M1 for EN 1999.

Dialog Box "Edit Material", Adjusting Partial Safety Factors

Options

The symbols in the "Options" column are used for different settings or modified values. They allow for a quick overview, for example, to identify the materials with adjusted properties.
