The 28 pages that link to Anisotropy, each with the reason it gives.
HardnessRelated: Crystallographic direction can make hardness differ across a single crystal.
PermittivityRelated: Anisotropic materials require permittivity to be represented by a tensor.
MicaRelated: Mica’s properties differ along its sheets and perpendicular to them.
Groundwater flowRelated: Layering and aligned fractures can make flow faster in some directions.
Carbon fibersRelated: Carbon fibers are much stronger and stiffer along their length than across it.
LaminationRelated: Layer orientation often makes a laminate stronger in some directions than others.
BoudinageRelated: Directional strength in a rock can influence boudin shape and orientation.
