Визначення параметрів термомеханічного стану термочутливих магнітотвердих феромагнітних тіл за умов дії квазіусталених електромагнітних полів

Abstract

An approach to the computer simulation of a thermo-mechanical behavior of magnetically hard ferromagnetic solids subjected to quasisteady electromagnetic fields is considered on the basis of the proposed earlier mathematical model of thermo-mechanical processes in polarizable and magnetizable electrically conductive solids exposed to external electromagnetic fields. High temperature induction heating of a hard ferromagnetic cylinder is considered. The numerical results obtained clearly indicate the necessity to account for the heat release due to magnetization, especially for small frequencies and temperatures less than the Curie point.
