Orthotropic material

Orthotropic materials are a specific type of anisotropic material that has unique mechanical properties in three mutually perpendicular directions. This means that their material properties (such as elasticity, strength, and thermal expansion) vary based on the direction in which they are measured. The term "orthotropic" typically applies to materials that exhibit different behaviors in three orthogonal principal material directions, which are usually referred to as the x, y, and z axes.
