Mar 12, 2022 · When a property is the same in all directions, the material is isotropic. When a property varies according to direction, the material is anisotropic. The terms come from the Greek isos (equal) and tropos (way). The an in “anisotropic” means “not.”.
An anisotropic object or pattern has properties that differ according to direction of measurement. For example, many materials exhibit very different physical or mechanical properties when measured along different axes, e.g. absorbance , refractive index , conductivity , and tensile strength .
Difference Between Isotropic And Anisotropic. Isotropic refers to the properties of a material which is independent of the direction whereas anisotropic is direction-dependent. These two terms are used to explain the properties of the material in basic crystallography.
Anisotropy, in physics, the quality of exhibiting properties with different values when measured along axes in different directions. Anisotropy is most easily observed in single crystals of solid elements or compounds, in which atoms, ions, or molecules are arranged in regular lattices.
ANISOTROPIC definition: 1. Something that is anisotropic changes in size or in its physical properties according to the…. Learn more.
Apr 20, 2017 · If the properties (mechanical, physical, thermal and electrical properties) of a material do not change with different crystallographic orientations, or in other words, the properties are direction independent, that material is called isotropic.
Jun 26, 2024 · Understand the nature of anisotropic behaviour in a range of properties, including electrical and thermal conductivity, diffusion, dielectric permittivity and refractive index, and be aware of a range of everyday examples. Be familiar with the use of representation surfaces.
Anisotropy is the property of substances to exhibit variations in physical properties along different molecular axes. It is seen in crystals, liquid crystals and, less commonly, in liquids. For example, consider the primitive cubic crystal lattice structure shown here.
The mechanical properties of anisotropic materials are different in each direction and asymmetrical at all their planes or axes. However, a subclass of anisotropic materials is orthotropic materials, which display symmetry between the two planes.
9.2.1.3 Anisotropy. Anisotropy refers to the property of a material exhibiting directionally dependent features and with its layered orthorhombic structure, BP is a unique 2DM in which electrons, phonons, and their interactions with photons behave in a highly anisotropic manner within the plane of the layers.
