In recent decades, there has been a significant rise in the utilization of composite materials for various engineering applications. These advanced offer potential to improve mechanical properties and vibration characteristics structural components. This particular study is dedicated enhancing performance coupled curved-curved beams that feature linear elastic mid-layer, achieved through incorporation carbon nanotubes (CNTs), graphene nanoplates (GNPs), oxide powder (GOPs). The governing equations system are solved using generalized differential quadrature (GDQ) method. While previous research primarily focused on use CNTs enhance behavior coupled-curved beams, this delves into multiple nanofillers purpose. An essential aspect modeling lies determining their equivalent properties. undertakes comparison between rule mixture (RoM) Halpin-Tsai methods calculating these properties, revealing frequencies derived from RoM method higher than those obtained approach. Additionally, highlights systems incorporating GNPs demonstrate at lower nanofiller volumes, with GOPs following ranking. However, hierarchy shifts volumes. arrangement within influenced by its boundary conditions, curvature bottom beam playing role affecting behavior. Increasing radius (R2) leads frequencies, which subsequently decrease R2 values.

Free vibration of point supported ring-stiffened truncated conical sandwich shells with GPLRC porous core and face sheets

Mechanics Based Design of Structures and Machines, Journal Year: 2023, Volume and Issue: 52(9), P. 6142 - 6172

Published: Oct. 26, 2023

As a first attempt, the vibrational behaviors of point supported truncated conical sandwich shells with circumferential stiffeners, graphene platelets reinforced composite porous core and face sheets (GPLRC-PC-FS) are investigated. The supports simulated using conventional elastic translational rotational springs, which can be easily converted to classical boundary conditions. sheets, stiffeners co-axially perfectly bonded, each these components by uniformly distributed randomly oriented (GPLs). motion equations derived zigzag shell theory based on first-order shear deformation (FSDT) in conjunction Chebyshev-Ritz method. results validated carrying out convergence study performing comparison studies existing solutions literature. After that, influences porosity its structures, GPLs weight fraction geometric dimensions, parameters shell, conditions, stiffener show that number plays an important role fundamental frequency considered shells. Moreover, it is found distribution pattern have considerable effects natural frequencies. Also, reveal adding very small amount GPLs, frequencies increase significantly.
