Effects of Coupled Fields on the Mechanical Response of Electrically Conductive Composites

In this work, the possibility for improvement of impact resistance of electric-current-carrying composite structures in the presence of an electromagnetic field is investigated. Governing equations describing the electro-magneto-mechanical interactions in anisotropic materials and the corresponding two-dimensional approximation for transversely isotropic plates are discussed. An efficient numerical procedure is developed to solve the resulting nonlinear boundary value problem for a long transversely isotropic current-carrying plate subjected to impact and pulsed electromagnetic loads. The numerical results show that the dynamic response of the plate highly depends on the magnitude and direction of the electromagnetic loads.
