Bridgman effect

The Bridgman effect (named after P. W. Bridgman), also called the internal Peltier effect, is a phenomenon that occurs when an electric current passes through an anisotropic crystal – there is an absorption or liberation of heat because of the non-uniformity in current distribution.

The Bridgman effect is observable in geology. It describes slip-stick behavior of materials under very high pressure.<ref>Griggs, David (1960). Rock Deformation (A Symposium). Geological Society of America. p. 339. ISBN 9780813710792. Retrieved 9 September 2017.</ref>
