The nonlinear dynamic response of the blast loaded magnetoelectroelastic multiphase porous (MEEMP) plates in the temperature environment is examined in this study. This research aims to investigate the impact of pyrocoupling and blast loads on the coupled nonlinear behaviour of smart MEEMP plates. The different volume fractions of piezoelectric and piezomagnetic phases constitute various volume fractions of MEE material. The kinematics of the plate is supposed to follow Reddy's higher-order shear deformation theory (HSDT). 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 (FE) methods, which is then solved using the direct iterative technique. The numerical examples are offered to show how gradient patterns, gradient index, and blast loading parameters affect the nonlinear dynamic response.
