Nonlinear bilateral caloric–electromechanical couplings in polycrystalline ferroelectrics

Abstract

AbstractThis research is about irreversible domain wall motion leading to a temperature change of the material. The materials are mostly subjected to high frequencies and large electrical loads, which is why insufficient heat dissipation can lead to undesirable temperature developments, so–called self heating. Predictions concerning polycrystalline material behavior are made by the condensed method.
