For the first time, isogeometric analysis (IGA) approach is used to model and analyze free forced vibrations of doubly-curved magneto-electro-elastic (MEE) composite shallow shell resting on visco-Pasternak foundation in a hygro-temperature environment. The MEE types include spherical shell, cylindrical saddle elliptical subjected blast load are investigated. Maxwell equation electromagnetic boundary conditions determine vary electric magnetic potentials. shell's equations motion derived from Hamilton's principle refined higher-order shear theory. Then, IGA method derive laws natural frequencies dynamic responses under various conditions. accuracy verified through reliable numerical comparisons. Aside this, impact input parameters vibration examined detail. These results may be useful design manufacture military structures such as warships, fighter aircraft, drones missiles.

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.
