Abstract Magneto-Electro-Elastic (MEE) Composites, as an innovative functional material blend, are composed of multiple materials, boasting exceptional strength, rigidity, and extraordinary magneto-electric interaction effect. This paper establishes a nonlocal modified couple stress (NL-MCS) magneto-electro-elastic nanobeam dynamic model. To accurately capture the intricate influences scale effects on nanostructures, model meticulously examines from two distinct perspectives: leveraging elasticity theory to elucidate softening phenomena in nanostructures stemming long-range particle interactions, employing reveal hardening attributed rotational behavior particles within structure. By incorporating Von Karman geometric nonlinearity, Reddy’s third-order shear deformation Maxwell’s equations, governing equations for nonlinear free vibration MEE nanobeams derived using Hamilton’s principle. Finally, two-step perturbation method is employed solve these equations. Two-step disintegrates solution process into stages, iteratively approximating refining solution, thereby progressively unraveling details enhancing precision systematic manner. explored under coupled magnetic-electric-elastic fields, with focus various factors that including length parameters, Winkler-Pasternak coefficients, span-to-thickness ratios, applied voltages magnetic potentials.

In this article, the application of an artificial neural network (ANN)-based machine learning (ML) strategy to predict coupled frequency geometrically skewed multiphase magnetoelectric (MME) composite plate exposed hygrothermal environment is presented. The ANN model trained using a dataset comprising more than one million simulations conducted in-house developed finite element formulation. underlying multiphysics governing equations are derived Hamilton's principle and higher-order shear deformation theory (HSDT). influence on elastic stiffness MME composites defined by empirical constants in constitutive relations. Four prominent combinations leading different relations have been considered study. Alongside, geometrical skewness fundamental also assessed. For training model, Levenberg–Marquardt optimization algorithm with 30 neurons along tangent sigmoid activation function used. tested unseen dataset, from data, it shown accurately natural maximum error 2.3%.
