Mathematical Modeling and Analysis of Thermostressed State of Bimetallic Plate Under Electromagnetic Action in the Mode with Pulse Modulated Signal

Abstract

The thermostressed state of a bimetallic plate under the electromagnetic action in the mode with pulse modulated signal (MPMS) at the resonant frequencies of the electromagnetic field is studied. There are established the critical values of the parameters of the electromagnetic action at which the bimetallic plate loses its load-carrying ability as a constituent element.

Thermomechanical behavior of an electrically conductive cylindrical implant under the action of external unstable electromagnetic fields

“…Time of action of unstable EMF is t i = t incr +t decr . Unsteady EMF, which is mathematically described by expression (24), has the character of impulsed EMF with amplitude modulation [8,9,[12][13][14][15][16][17]. Substituting the expression (24) of the function H + z (t) in the relation ( 3)-( 23), we obtain the expressions of Joule heat Q, radial component F r of the vector of ponderomotive force F and temperature T , radial displacements u r and corresponding stresses σ jj (j = r, ϕ, z) under the action of unstable EMF.…”
