Abstract

The influence of various micro-topological textures of Barium Titanate and Cobalt Ferrite (BaTiO₃–CoFe₂O₄) composites on the nonlinear dynamic response of the blast loaded magneto-electro-elastic plates in the temperature environment is examined in this study. The novelty of the work lies in considering the influence of pyrocoupling associated with the micro-topological textures in the analysis. Three different forms of micro-topological textures such as face-centred cubic, body-centred cubic and simple cubic structures are considered in this evaluation. The kinematics of the plate is supposed to follow Reddy's higher-order shear deformation theory. Also, von-Karman's equations are used to bring nonlinearity into the model. The blast loads are calculated using an exponential function and are expected to be dispersed evenly across the plate's surface. The principle of virtual work is used to develop the governing equations using finite element methods, which are then solved using the direct iterative technique. The numerical examples show the influence of micro-topological textures, electromagnetic circuits, coupling effects, and blast loading parameters on the nonlinear dynamic response.
