M. To create a material definition

To create a new isotropic material definition for use with your model, use the following procedure.

You may want to set the input units to a familiar set of units for defining materials before creating a new material definition.

STAAD.Pro includes a set of predefined materials for concrete, aluminum, steel, and stainless steel.

Select the Materials page in the Analytical Modeling page control bar.
The Material - Whole Structure dialog and the Materials table open.
In the Material - Whole Structure dialog Isotropic tab, click Create.
The Isotropic Material dialog opens.
Type a Title to identify the material. This title must be different than the predefined material names or any other existing user-defined material name.
Type the values of the Material Properties used for analysis:
- Young's Modulus, E
- Poisson's Ratio, ν
- Density, γ
- Thermal Coefficient, α
- Critical Damping
- Shear Modulus, G
Select the Type of Material from the drop-down list.
Type the strength values in the Design Properties section. The fields corresponding to the selected material type are active.
Click OK.

The material definition is now added to the Materials table and is available for selecting when assigning shapes and in Material - Whole Structure dialog.
