The elliptical cavity problem along with other similar cavity problems are important in the study of this effect and in two-dimensions, the Lekhnitskii and Stroh formalism can both be used to describe it.
The elliptical cavity problem along with other similar cavity problems are important in the study of this effect and in two-dimensions, the Lekhnitskii and Stroh formalism can both be used to describe it. In the linear approximation of this effect, there are 18 independent namesake constants to solve for. That approximation couples the equation setting the electric displacement field equal to the permittivity of free space times the electric field plus polarization with Hooke's law. Although not pyroelectricity, ferroelectric materials exhibit this effect. This effect's converse is electrostriction and it only occurs in materials without a center of symmetry. Used in cigarette lighters and sonar, for 10 points, name this effect is found in materials like quartz that causes an electric field or potential to be generated in response to mechanical strain.
