Thermal Options for Material Definition
Different options appear on the Thermal tab of Material Definition dialog box, depending on the material type you choose:
Isotropic — a material with an infinite number of planes of material symmetry, making the properties equal in all directions. You enter a single value for each property.
Orthotropic — a material with symmetry relative to three mutually perpendicular planes. You enter three values for each property.
Transversely Isotropic — a material with rotational symmetry about an axis. The properties are equal for all directions in one plane, the plane of isotropy. You enter two values for each property—one for the plane of isotropy, and one for the remaining principal material direction.
The Creo Parametric default material library contains isotropic materials only. Additionally, if you selected Edge/Curve as a geometry type, then the Orthotropic and Transversely Isotropic options are unavailable.
