In this work, free vibration and transient response of porous metal foam magneto-electro-elastic (PMF-MEE) curved nanobeam with elastic boundary conditions (BCs) using an isogeometric analysis (IGA) based on nonlocal refined higher-order shear beam theories (HSDT) are investigated. The variation electric magnetic potentials through the thickness direction is determined by Maxwell equation magneto-electric condition. new point paper that it does not use traditional conditions, but instead, first last positions linked system consisting transrational springs rotational stiffness controlled to give arbitrary conditions. Besides, coefficients vary like other material properties. Hamilton's principle applied establish governing equations motion. Newmark direct integration method derive dynamic responses including deflection phase trajectory. A comprehensive parametric study carried out evaluate influence input factors natural forced oscillation capabilities PMF-MEE nanobeams. findings may benefit for design intelligent structures made materials.

This paper uses the analytical method with arbitrary boundary conditions to model and analyze free vibrations of multi‐directionally functionally graded porous (MFGP) doubly‐curved shallow shells resting on Pasternak foundation in a temperature environment. It is anticipated that all mechanical parameters, except Poisson's ratio, will change direction length, width, thickness. To comprehensively describe shell's displacement, strain, stress fields, modified first‐order shear deformation theory (FSDT) an assumption cosine distribution stresses has been developed. The fact enhanced FSDT does not require use correction at two faces zero are theory's most significant advantages. Using Hamilton's principle improved FSDT, one may get governing equation for vibration analysis MFGP shells. Galerkin approach proposed solve various conditions. trustworthiness article evaluated via its publication model's several special cases. From this point on, collection findings about natural frequency identified shown form tables graphs. results provided manuscript can be used as benchmark solution further studies far behavior concerned.
