Material Constant dialog
Used to specify individual material constants of the materials of which members and elements are comprised.
Opens when a constant name is selected from the Constants tool in the Materials group on the Specifications ribbon tab. A separate dialog is used to define each constant value.
Built-In Material Constants
For E, G, POISSON, DENSITY, ALPHA, and CDAMP, built-in material names can be entered instead of a value for f1. The built-in names are STEEL, CONCRETE, & ALUMINUM. Appropriate values will be automatically assigned for the built-in names.
