Thermally stressed state of the layer under the influence of currents periodic with respect to the longitudinal coordinate

To evaluate the impact of the important non-uniformity technological factor of the external electric current distribution on the low-temperature heating parameters of flat ferrite elements, taking into account the stressed state (strength characteristics), a model problem is considered to determine and study the thermomechanical behavior of the ferrite layer under the influence of a quasi-steady electromagnetic field created by the current flowing in the current-carrying plane, the density of which changes sinusoidally along the longitudinal coordinate.  In accordance w

Mathematical model for temperature estimation forecasting of electrically conductive plate elements under action of pulsed electromagnetic radiation of radio-frequency range

A mathematical model for determining the temperature of an electrically conductive plate element under the action of pulsed electromagnetic radiation of the radio-frequency range is proposed.  This model allows us to take into account the influence of the process of thermoelastic energy dissipation on the forecasting of the value of temperature in addition to the joule heat.  This process is determined by thermal expansion and the action of poendromotive forces arising in the element.  This approach allows us to predict a decrease in the error of temperature determination.  On this basis, t
