The investigation of graphene-reinforced porous composites has garnered significant interest due to their exceptional mechanical, thermal, and electrical properties, positioning them as promising materials for advanced structural applications. To fully harness the potential these materials, numerical modeling becomes essential understanding behavior optimizing performance specific engineering In present study, non-linear bending response functionally graded (FG) circular sandwich plates reinforced with graphene platelets is systematically analyzed under varying boundary conditions. are subjected a uniform transverse load thermal gradient, distributions porosity along thickness. effective material including Poisson’s ratio, computed using Gaussian random field scheme in conjunction Halpin-Tsai micromechanical model. governing equations motion derived from Von Kármán’s relations, utilizing both first-order shear deformation theory (FSDT) modified higher-order (MHSDT). These subsequently solved dynamic relaxation (DR) coupled finite difference methods. validate results, comparisons existing literature element method (FEM) conducted, ensuring accuracy reliability obtained solutions. A comprehensive parametric study performed investigate influence various factors, conditions, distribution patterns, variations, thickness-to-radius on composite plates.

Vibration and aeroelastic instability analysis in GPL-porous multi-layered beam with the rotation effect

International Journal for Computational Methods in Engineering Science and Mechanics, Год журнала: 2024, Номер 25(6), С. 357 - 380

Опубликована: Июль 4, 2024

This research studies the vibrations and instability of a rotating three-layer beam under aerodynamic forces consisting two functionally graded (FG) composite surfaces porous intermediate layer. Linear poroelasticity theory is used for modeling layer while Young's modulus density vary along thickness. Equivalent coefficients graphene nanoplatelets-reinforced (GPLs) are extracted by modified Halpin-Tsai theory, according to five different configurations. The equations motion in GPL-porous multi-layered derived using Euler–Bernoulli (EBB), Timoshenko (TB), Reddy's higher-order shear deformation (HSDT) theories, as well energy method Hamilton's principle. most important results show effect reinforcements their configurations, porosity its distribution, speed rotation on natural frequency, critical flutter point, loss factor beam. unique properties GPL-reinforced materials facilitate design components capable effectively managing dynamic loads resisting aeroelastic instabilities. more efficient, reliable, durable systems across various industries.
