Modeling of the Temperature Regimes in a Layered Bimetallic Plate under Short-Term Induction Heating

A mathematical model for determining the temperature field of a bimetallic plate with plane-parallel boundaries during short-term induction heating by non-stationary electromagnetic is proposed. Initial boundary value problems parameters and are formulated. The component magnetic intensity vector that tangential to base were selected as defining functions. We used an approximation functions in each layer quadratic polynomials thickness coordinate Laplace transform integral over time. General solutions formulated under uniform action obtained. Based on them, was numerically analyzed depending its amplitude-frequency duration.
