Using the third-order shear deformation theory (TSDT), this research investigates loss in sound transmission through air-filled rectangular double-walled sandwich smart magneto-electro-elastic (MEE) plates with a porous functionally graded material (PFGM) core layer, presence of external mean airflow and subjected to uniform non-uniform temperature distributions. Multiple profiles are evaluated order correctly capture impact rises over thickness. Based on power-law model, three different types uneven porosity distributions considered for PFGM layer. These should change along in-plane thickness directions. Hamilton's concept is used achieve derivation vibroacoustic equations as coupled relations. The (STL) equation obtained by using double Fourier series combination an analytical method, i.e., second velocity potential. produced solution terms accuracy precision comparing it other accessible data from previous study. effects initial electric magnetic potentials, distributions, incidence angles, acoustic cavity depth, changes profile STL shown parameter investigations.

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.

Published: June 26, 2024

Abstract This study investigates the behavior of free vibrations in a variety porous functionally graded nanobeams composed ferroelectric barium-titanate (BaTiO 3 ) and magnetostrictive cobalt-ferrite (CoFe 2 O 4 ). There are four different models nanobeams: uniform porosity model (UPM), symmetric (SPM), concentrated bottom region (BPM), top (TPM). The nanobeam constitutive equation calculates strains based on various factors, including classical mechanical stress, thermal expansion, electroelastic properties, nonlocal elasticity. investigated effects factors vibration nanobeams, thermo-magneto-electroelastic coupling, electric magnetic field potential, features, models, changes volume. temperature-dependent properties BaTiO CoFe have been recently explored literature for first time. dynamics nanosensor beams greatly influenced by characteristics. As ratios decrease, dimensionless frequencies decrease increase, respectively, material grading index. were parameter, external temperature, causing them to rise. On other hand, slenderness ratio potential caused drop. volume has depending model.

Published: Feb. 1, 2024

Negative Poisson's ratio (NPR) auxetic metamaterials are attracting significant attention because of their peculiar and interesting mechanical features. Using geometrically von-Karman nonlinear factors Mindlin plate theory, a smart multiscale hybrid (GPL/CF/PVDF) sandwich with unique two-type functionally graded graphene origami (FG-GOA) is investigated here for its vibrational behavior. The present properties the electro-elastic layers were established using Halpin–Tsai (HT) model rule mixing (ROM). Hamilton's principle, Maxwell's law, von Karman used to determine governing equations piezo plate. subsequent step use generalized differential quadrature (GDQ) technique discretize motion Results show that FG-GOA plates exhibit hardening nonlinearity. Nonlinear ratios frequencies natural frequency intelligent also measured by electric voltage, weight fraction GPL, volume carbon fibers. Furthermore, effect porosity coefficient, GOri folding degree, core height, nanocomposite (SHNC) layer's height on calculated displayed each figure.
