Select Materials in the Job Preferences dialog and click the Modification button. Select the Aluminum tab to access the following parameters.

Define the following:
Name
The representative name of the defined aluminum.
Note: The material name must be assigned before the Add button is pressed.
Description
The representative description of the defined aluminum.
Elasticity
- Youngs modulus - the Young's modulus value for the defined aluminum.
- Poisson ratio - the Poisson's ratio for the defined aluminum.
- Shear modulus - the shear modulus for the defined aluminum. This recognizes the influence of shear forces on structure deformation.
Resistance
- Characteristic / design resistance - the characteristic or design resistance values of the defined aluminum.
- Reduction factor for shear - the shear coefficient for the defined aluminum. Note: The shear coefficient is used during structure calculations when shear deformation calculations are required.
Others
- Force density (unit weight) - the density (unit weight) of the defined aluminum.
- Thermal expansion coefficient - the thermal expansion coefficient for the defined aluminum.
- Damping ratio - the damping ratio of the defined aluminum.
