Yes, wood is a naturally anisotropic material. It has 3 different orientations:
- Longitudinal - parallel to the grain
- Radial - across the growth rings
- Tangential - tangent to the growth rings
Wood
The most commonly used material for railings is wood. The reason is simply because wood is inexpensive and very easy to install. If one is making a deck railing, it is highly suggestive to use wood for material.
Wood flooring refers to any material that is meant to be flooring and that is made out of lumber. You can get solid wood flooring. Be careful; don't confuse laminate, vinyl, or vaneer floors for wood floors.
The tensile strength of a material is the value at which the material fails when subjected to a tensile force. (Tensile means a force pulling the wood fibers lengthwise, as opposed to a compressive force.) There are a lot of different types and load cases for wood, so there is not one answer to this question. For example, wood used outside will fail at a lower load than wood inside. Wood is also anisotropic, i.e. it has different strength in different directions. Example values of tensile strength vary anywhere from 175 pounds per square inch for Utility Grade pine to 1400 psi for Dense Select Structural grade Douglas Fir. A good reference for material strength data for most species and grades of commerically available wood can be found in the American Institute of Timber Construction handbook.

An anisotropic material is a material which does not behave the same way in all directions. Take wood for example. Wood is very strong along the grain. Against the grain, however, it will easily break. The opposite of an anisotropic material is an isotropic material. Most metals (steel, aluminum) are isotropic materials. They respond the same way in all directions.
Nonisotropic or anisotropic refers to a medium in which some characteristics depends on the direction in which the medium is studied. A very common anisotropic material is wood. It is much easier to split it along its grain than across the grain.
Isotropic materials have the same properties in all directions, while anisotropic materials have different properties depending on the direction. An isotropic material has uniform properties regardless of the direction in which it is measured, making it easier to analyze and design with. Anisotropic materials, such as wood or composites, have varied properties based on their orientation, which can lead to different behaviors under stress.
Most of the materials can be considered elastic at least for a specific range. For example, Wood is elastic when we compare it with glass. Their modulus of elasticity cannot be calculate. However;It is anisotropic material. (its elasticity will be change if your loading parallel to its fibers or perpendicular.)
Anisotropic materials have different properties in different directions. For example, wood has different properties along its grain compared to across the grain. This can result in variations in strength, elasticity, conductivity, and other characteristics depending on the orientation of the material.
Anisotropic properties are direction dependent because the material exhibits different physical properties (such as conductivity, elasticity, or optical properties) along different crystallographic axes. This is due to the asymmetry in the arrangement of atoms or molecules within the material, leading to varying responses to stimuli along different directions.
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.
When a light ray enters an anisotropic material, the ray can split into two perpendicular rays with different velocities and directions due to the varying optical properties in different directions. This phenomenon is known as birefringence, and the two resulting rays are called ordinary and extraordinary rays.
Non-isotropic materials are those that exhibit different properties in different directions. This means that the material's characteristics, such as strength, thermal conductivity, or electrical conductivity, vary depending on the direction in which they are measured. Anisotropic materials are common in various applications, such as composites, crystals, and wood.

Anisotropic is when you view graphics and images at an oblique angle. It's like knowing what an object is in one direction but then your value of the object changes when viewed in different directions.
