dc.description.abstractThis paper is concerned with thermo-elasto-plastic dynamic response of a conductive plate in a magnetic pulse field. The influence of the strain rate effect and the temperature effect are taken into account for the electromagnetic elasto-plastic dynamic transient response and deformation of the conductive plate which made of strain-rate sensitive materials. The Johnson-Cook model is employed to study the strain rate effect and the temperature effect on the deformation of the plate. Basic governing equations are derived for electro-magnetic field considering the eddy current. The analysis includes the elastoplastic transient dynamic response and the heat transfer of a conductive rectangular plate, and then an appropriate numerical code based on the finite element method to quantitatively simulate the electro-magneto-elasto-plastic mechanical behaviors of the conductive rectangular plate. The numerical results indicate that the strain rate effect has to be considered for the conductive plates, especially for those with high strain rate sensitivity. Comparison of the influence of the temperature effect on the deformation of the plate with that of the strain rate effect shows that the influence of the temperature effect on the deformation of a plate is not significant.en
