Assign material dialog

This dialog is used to assign materials to members, surfaces, or surface regions. Existing materials in the model can be used or new ones can be added to the model.

Opens when either:
  • the Material tool in the Properties group on the Member ribbon tab is selected
  • the Material tool in the Properties group on the Surface ribbon tab is selected
  • the Material tool in the Properties group on the Region ribbon tab is selected

Source Select one of the following options:
  • Catalog - Used to select materials from the Section Property Catalog.
  • Model - Used to select catalog materials previously added to your current model.
  • User Database - Used to select custom materials previously saved in your user database.

Standard Type

Property Value
Type Select the type of member to use:
  • Standard — Used to select a standard material grade from the Section Property Catalog.
  • Custom — Used to create a custom steel or concrete material grade.
  • Generic — Used to create a generic material.
Country Select the country where the catalog shape is produced.
Material type Select the type of material used from the drop-down list of materials for the selected country.
Material name Select the material grade name from the drop-down list.

Custom Type

Property Value
Country Select a country with which to associate the custom material.
Specification Select the appropriate material specification to which this custom material will be added.
E (Steel only) Specifies the modulus of elasticity (i.e., Young's Modulus).
G (Steel only) Specifies the shear modulus.
Mu "Poisson's ratio", the ratio of transverse strain to strain in the direction of load.
Gamma The weight density of the material.
Alpha Coefficient of thermal expansion.
Fy (Steel only) Yield strength.
Fu (Steel only) Ultimate tensile strength.
Fck (Concrete only) Ultimate compressive strength of concrete.
Fcu (Concrete only) Ultimate compressive strength of concrete.
CDAMP Damping ratio to be used in computing the modal damping by the composite damping method in a dynamic analysis when CDAMP has been specified. Damping must be in the range of 0.001 to 0.990.
Name Type a name used to later identify the custom material.

Generic Type

Property Value
Material name Type a unique name used to identify the generic material.

Additionally, you must define E, G, Mu, Gamma, Alpha, and CDAMP values for generic materials. See the description for custom materials for definitions.

Existing Material

If you select either Model or User database as the Source, you can then select an existing material from your model or custom user database.

Property Value
Type For User Database materials, select either Custom or Generic material types.
Material type For Custom materials, select the specification type.
Name Select the existing material name from the list.
