ELECTROMAGNETIC AND STRUCTURAL COUPLED ANALYSIS WITH THE EFFECT OF LARGE DEFLECTION

This paper describes a coupled finite element analysis for the eddy cu rrent and the structure. A formulation is presented considering the ef fect of the large deflection of shell structures by the total Lagrangi an formulation. Both matrix equations for the eddy current and the str ucture are solved simultaneously using coupling sub-matrices. A couple d problem of a cantilever bending plate is analyzed. Based on the anal ysis results, the influence of the large deflection on the coupling ef fect is discussed. The condition that the large deflection analysis is required is examined through some parametric analyses.
