A material is orthotropic if its mechanical or thermal properties are unique and independent in three mutually perpendicular directions. Examples of orthotropic materials are wood, many crystals, and rolled metals.

By definition, an orthotropic material has at least 2 orthogonal planes of symmetry, where material properties are independent of direction within each plane. Such materials require 9 independent variables (i.e. elastic constants) in their constitutive matrices.
An orthotropic material is a type of material that has mechanical properties that vary based on the direction of load application. These materials have three mutually perpendicular axes of symmetry along which the material properties differ. Orthotropic materials are commonly found in composites and natural materials like wood.
an orthotropic material is one that has the different materials properties or strength in different octhogonal directions, but properties of anisotropic material being directionally dependent. thus Orthotropic materials are anisotropic.
Resistivity is an intrinsic property of a material and is not affected by the dimensions of the material. Resistivity is determined by the material's composition and structure. The resistivity of a material remains constant as long as the material is uniform.
When a cold material interacts with a hot material, heat will transfer from the hot material to the cold material until they reach thermal equilibrium. This will result in the hot material cooling down and the cold material heating up. The rate of heat transfer will depend on the temperature difference between the two materials and their thermal properties.
Current through a material can change by varying the voltage applied across the material, altering the resistance of the material, or modifying the temperature of the material. These changes can affect the flow of electrons through the material and, consequently, the current passing through it.
When light encounters an opaque material adjacent to a transparent material, most of the light is reflected and absorbed by the opaque material, while a small amount may be transmitted through the transparent material. The opaque material blocks the passage of light, creating a shadow on the transparent material.
