A new 2D model for electrically conductive laminated composite plates subjected to mechanical and electromagnetic loads has been developed. The model is based on an extension of the classical lamination theory that utilizes the Kirchhoff hypothesis of nondeformable normals combined with physics-based simplifying hypotheses for the electromagnetic field. Within the developed model a problem of the dynamic response of laminated composite plates subjected to the dynamic transverse mechanical loading, pulsed electric current, and magnetic field is considered. The numerical results show that the applied electromagnetic field can change the amplitude and pattern of vibrations of the laminated plate. A damping effect is observed for rather large external magnetic inductions. It has also been found that the electromagnetic field effects are more apparent in a unidirectional composite plate than in a cross-ply plate.
