Breakdown in Solid Dielectrics - BU

When solid dielectrics are subjected to high electric fields, failure occurs due to electrostatic compressive forces which can exceed the mechanical compressive strength. If the thickness of the specimen is d0 and is compressed to thickness d under an applied voltage V, then the electrically developed compressive stress is in equilibrium.

Section 4: Electrostatics of Dielectrics

This property of dielectrics is known as polarizability. Basically, polarizability is a consequence of the fact that molecules, which are the building blocks of all substances, are composed of both positive charges (nuclei) and negative charges (electrons). When an electric field
