FINITE ELEMENT ANALYSIS FOR WEAKLY COUPLED MAGNETO – THERMO – MECHANICAL PHENOMENA IN SHELL STRUCTURES

Abstract

In a previous paper it was shown that, the use of the surface impedances concept, widely used already, can contribute to the construction of a universal model for eddy currents modeling in thin layers. This is the most fundamental part for a systematic approach on constructing an appropriate type of finite element analysis for weakly coupled magneto - thermo - mechanical phenomena in shell structures. At this point it would be very interesting, to remind, that this technique has been initially used for thin layers modeling. Such a structure can be represented by two surfaces with self - impedances Zaa and Zbb respectively, accompanied by a transfer impedance Ztr taking into account the interdependence of the phenomena on the two surfaces. Hence, the previous paper was devoted to the presentation of this universal model, which is accompanied by a new type of elements for its implementation. A second and a third part followed. The second part dealt with one directional coupling of magnetic and thermal phenomena, whilst the third one with one directional coupling of magnetic and mechanical phenomena very briefly and this the point from which, this paper starts.
