THERMAL STRESSED STATE OF A CONDUCTING BALL UNDER THE ACTION OF PULSED ELECTROMAGNETIC FIELDS

We pose the dynamic centrally symmetric problem of thermomechanics for a continuous conducting ball subjected to the nonstationary uniform electromagnetic action and propose a method for its solution based on the use of the cubic approximation of the azimuthal component of the magnetic vector and the radial component of the stress tensor in the radial coordinate. The solution of the problem is obtained and the thermal stressed state of the ball under the action of electromagnetic pulses is numerically investigated.
