quasi-isotropic

Updated: June 7, 2025

These considerations also apply to quasi-isotropic bodies which are, in fact, networks of crystals. Certain occasional deformations which are produced and disappear slowly may be considered as intermediate between elastic and permanent deformations. Of these, the thermal deformation of glass which manifests itself by the displacement of the zero of a thermometer is an example.
