Add / Assign material dialog
This dialog is used to add or 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.
The Add materialdialog opens when the Add
material tool is selected in the Sections and
Materials group on the Catalog ribbon tab.
Standard Type
Property | Value |
---|---|
Specification | Select the type of material used from the drop-down list of materials. |
Name | Select the material name from the list. Some materials, such as steel, have multiple entries representing different material grades. |
Custom Type
Property | Value |
---|---|
Specification | Select the appropriate material specification to which this custom material will be added. |
Name | Type a name used to later identify the custom material. |
E | (Steel only) Specifies the modulus of elasticity (i.e., Young's Modulus). |
G | (Steel only) Specifies the shear modulus. |
Possion | "Poisson's ratio",ν, the ratio of transverse strain to strain in the direction of load. |
Density | The weight density of the material. |
Alpha | Coefficient of thermal expansion. |
Damp | 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. |
Fy | (Steel only) Yield strength. |
Fu | (Steel only) Ultimate tensile strength. |
Ry | (Steel only) Yield strength ratio |
Rt | (Steel only) Tensile strength ratio |
Fcu | (Concrete only) Ultimate compressive strength of concrete. |
Generic Type
Property | Value |
---|---|
Material name | Type a unique name used to identify the generic material. |
Additionally, you must define E, G, Poisson, Density, Alpha, and Damp 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. |
Specification | For Custom materials, select the material type. |
Name | Select the existing material name from the list. |
