Select Materials in the Job Preferences dialog and click the Modification button. Select the Concrete tab to access the following parameters. 
Define the following: 
Name 
The name of the defined concrete. 
Note: The material name must be assigned before the Add button is pressed. 
 
Description 
A description of the defined concrete. 
 
Elasticity
- Young modulus - the value of Young's modulus for the defined concrete. 
 
- Poisson ratio - the value of Poisson's ratio for the defined concrete. 
 
- Shear modulus - The shear modulus for the defined concrete. This recognizes the influence of shear forces on structure deformation. 
 
 
Resistance
- Characteristic / design resistance 
 
- Sample type (cylindrical or cubical) 
 
 
Others
- Force density (unit weight) - the density (unit weight) of the defined concrete. 
 
- Thermal Expansion Coefficient - the thermal expansion coefficient for the defined concrete. 
 
- Damping Ratio - the damping ratio for the defined concrete.
