FEA and 'weakest-link' analysis of dielectric strength of polycrystalline alumina.

The article reports on a method to evaluate dielectric properties of alumina, referencing to a paper that was published in a 2013 issue of the "Journal of the American Ceramic Society." Topics discussed include alumina as an insulator, the occurrence of punctures, and the challenge to measure dielectric strength. Also mentioned are finite-element analysis (FEA), electric field distribution, and surface defects.
