This work presents an analysis of nonlinear vibration in Function Graded Magneto-Electro-Elastic (FG-MEE) plates subjected to mechanical, electrical, and magnetic loads using the nonlocal stress theory approach. In this study two types of MEE plates, namely BaTiO3 and CoFe2O4 were considered. The basic equations are derived using classical plate theory with nonlocal stress theory and are solved using the Galerkin method and Runge-Kutta method. We investigated the effects of nonlocal parameters, materials, and geometrical characteristics on the natural frequencies and nonlinear vibration of the FG-MEE microplates. \

To measure and evaluate the impact of vibration on the surrounding buildings and structures during highway rock burst removal and to formulate scientific and reasonable protective technical measures, the authors used the blasting perilous rock removal project of the K2227+920–K2228+000 section of the Shaanxi G316 road as a case study. The application of frequency modulation blasting vibration damping technology adopting digital electronic detonators was investigated. The difference in vibration peak and frequency between the perforation-by-hole initiation of the detonator and the frequency modulation initiation of the digital electronic detonator is compared. The results showed that by adopting an accurate delay of digital electronic detonators and the damping scheme of adjusting the blasting vibration frequency using the electronic detonators a reduction in blasting vibration velocity can be achieved. For an unchanged blasting scale, hole mesh parameters, and explosive unit consumption, the total blasting time was adjusted in the test. Compared to the hole-by-hole initiation, the blasting vibration velocity at a pier of the G85 Baohan highway bridge located 52 m away was reduced from 0.367 cm/s to 0.229 cm/s, a decrease of 36.7%. The field test demonstrated that frequency modulation and vibration attenuation using digital detonators can reduce blasting vibrations and effectively reduce the influence of blasting construction on surrounding buildings and structures.

This work presents a detailed investigation of the effect of auxeticity synergised with the pyro-coupling behaviour of multiphase magneto-electro-elastic (M-MEE) composites using a finite element (FE) framework. The nonlinear deflection and bending problems of sandwich plates with auxetic core and M-MEE skins subjected to multi-physics load (electric, magnetic and thermal) are probed. The plate kinematics is governed by Reddy’s higher-order shear deformation theory (HSDT). The nonlinear relation between the strains and displacements is established through von-Karman’s nonlinear relations. The temperature profiles are considered linearly and nonlinearly varying across the thickness of the plate. Various parametric studies presented in this article highlight the influence of the auxetic cell inclination angle, rib-length ratio, rib thickness, the plate-to-core ratio etc., associated with the pyro-coupling on the nonlinear deflection and bending of sandwich plates. The results reveal that the plate deflection, bending behaviour and degree of pyro-coupling significantly depend on the auxetic unit cell dimensions and magnitude of electro-magnetic loads. The significant influence of temperature profiles on the pyro-coupling are witnessed at lower auxetic cell angle. The nonlinear deflections of the sandwich plate and hence the potentials developed tend to improve with the lower values of plate-to-core ratio and rib thickness. The prominent outcomes of this work related to integrated effects of auxeticity and pyro-coupling are not yet reported in the open literature and are deemed to be utilised as a future reference.
