Electrostrictive stresses near crack-like flaws
TL;DR: In this paper, the effect of an elliptical through flaw in an infinite isotropic body is considered and the results are used to show that a flaw-like crack in a material with a very high dielectric constant can be treated by fracture mechanics as an impermeable slit crack when the flaw aspect ratio is an order of magnitude greater than the ratio of dielectrics permittivities.
