The longitudinal coefficient of this phenomenon and its quadratic dependence can be accounted for by the Preisach Model.
The longitudinal coefficient of this phenomenon and its quadratic dependence can be accounted for by the Preisach Model. A form of Saint- Venant's Principle may be applied to the helical and linear forms of this effect. It results in strain directly proportional to applied field and not proportional to the square of the field like electrostriction, its converse process. Seen prominently in barium titanate and tourmaline, and other ceramics lacking inversion centers, it was discovered in Rochelle salts by the Curie brothers. The opposite of mechanical distortion, FTP, name this effect exemplified by the production of voltage across the face of a quartz crystal in response to applied stress.
