In the Material Definition dialog box, enter values for the Young's Modulus (the modulus of elasticity) of the material. You can define this property or assign a parameter to the property. You can either type a value or right-click to assign a Parameter as appropriate.

For orthotropic material properties, enter positive values for:

These values represent the Young's Modulus along each of the three principal directions of the material.

For transversely isotropic material properties, enter positive values for the following two Young's Modulus values:

These values represent the Young's Modulus along each of the three principal directions of the material, with equal values in directions 2 and 3.
