anizotrópiáját

Anizotrópia, a physical property of materials, describes the directional dependence of physical properties. This means that a material's characteristics, such as its strength, thermal conductivity, electrical resistance, or optical properties, can differ depending on the direction in which they are measured. For instance, a crystal might be easier to cleave along one plane than another, or light might travel at different speeds through it depending on its polarization and direction.

This phenomenon stands in contrast to isotropy, where properties are uniform in all directions. Isotropic materials behave the same regardless of the orientation of measurement. Anizotrópia is a common feature in many natural and engineered materials. Examples include wood, which is stronger and stiffer along the grain than across it, and many composite materials, where the arrangement of reinforcing fibers dictates directional properties. Crystalline structures, due to their ordered atomic arrangements, often exhibit anizotrópia. The manufacturing process can also induce anizotrópia, as seen in rolled metals where the alignment of grains leads to directional mechanical behavior. Understanding and controlling anizotrópia is crucial in fields like materials science, engineering, and physics for designing and utilizing materials effectively.
