Abstract :
A finite element technique is described that fully couples structural and electromagnetic analysis in the time domain. One finite element model,with both linear and nonlinear structural and electromagnetic material properties, is solved in two or three dimensions. Displacements computed versus time for the TEAM12 eddy current 3D problem and for a nonlinear axisymmetric solenoid are shown to agree closely with measurements
