This page documents an OPTIMADE Property Definition. See https://schemas.optimade.org/ for more information.
ID: https://schemas.httk.org/defs/v0.1/properties/mechanics/universal_anisotropy_index
Definition name: universal_anisotropy_index
Property name: Universal anisotropy index
Description: The universal elastic anisotropy index A^U = 5 G_V/G_R + K_V/K_R - 6 (dimensionless); zero for an elastically isotropic crystal.
A null value means the quantity is not available or not recorded.
Type: float
Implementation requirements:
- Support: OPTIONAL support in implementations, i.e., MAY be null.
