The present article deals with the application of refined plate theory and surface effects to investigate nonlocal free vibration behavior a functionally graded nano-plate composed two piezoelectric face sheets resting on Orthotropic Visco-Pasternak. Surface are applied using piezoelectricity stress-strain gradient theories. effects, quasi-3D higher-order theory, neutral position in-plane mechanical preloads considered study sandwich core in this for first time, simultaneously. size-dependent governing equations derived based 2D 3D Hamilton's principle different boundary conditions studied investigated according semi-analytical solution method. Comparing results models, local non-local also, examining foundations simultaneously can be said as one innovations current research. Finally, parametric is presented examine parameters such small scale parameters, preloads, thickness stretching position, non-homogeneous coefficient, voltage, foundation constants, conditions, geometrical ratios theories details. It indicated that inclusion leads significant influence three-layered nano-scale plates. may provide useful guidance design development next generation nano-devices.

Investigation of moving load-induced vibrations in layered functionally graded Terfenol-D beams: a differential quadrature method and analytical approach

Mechanics Based Design of Structures and Machines, Год журнала: 2024, Номер 52(12), С. 10256 - 10272

Опубликована: Май 23, 2024

The paper investigates the potential of full-sinusoidal Fourier series as a solution form for deflection layered functionally graded beams associated with smart actuators, drawing on fundamental principles classical theory. current method simplifies difficult beam problem to set linear algebraic equations by using Duhamel integration technique and orthogonality trial function. study takes into account generalized boundary conditions moving forces, which are seldom discussed in previous research. Under action load, value integrated Terfenol-D is efficiently addressed approach combined differential integral quadrature. may be easily achieved adjusting stiffness restraining springs. significant agreement between quadrature underlines efficiency accuracy both methods. Furthermore, influences various crucial physical characteristics natural frequencies essential flow velocities explored, including stiffness, foundation parameters, geometric parameters.

Buckling analysis of thin-walled laminated composite or functionally graded sandwich I-beams using a refined beam theory

Mechanics Based Design of Structures and Machines, Год журнала: 2024, Номер unknown, С. 1 - 21

Опубликована: Июнь 30, 2024

This study presents the buckling and lateral torsional behaviors of thin-walled laminated composite or functionally graded sandwich I-beams. A refined beam model (RBT) based on 3D Saint-Venant (SV) solution is used in this to formulate problem. allows for a realistic analysis beams with arbitrary cross-sections free from limitations classical theories. The displacement models establish consistent 1D theory that accurately captures essence cross-section's nature. governing consider cross-section deformations, including out plane warpings distortions derived SV associated vibrational behavior. Furthermore, user-friendly numerical tool called CSB (cross-section analysis) facilitate implementation method. results are examined detail compared previous works investigate influence boundary conditions, angle-ply, shear effects, span-to-height ratio, material distribution critical loads demonstrate RBT efficiently analyze I-beams under different conditions. some new presented as reference values future.
