Simple first-order shear deformation theory for free vibration of FGP-GPLRC spherical shell segments

Mechanics of Advanced Materials and Structures (2023)

Van-Loi Nguyen Suchart Limkatanyu Huu‐Tai Thai Jaroon Rungamornrat

AbstractThis study presents a free vibration analysis of spherical shell segments using simple first-order shear deformation shell theory (S-FSDT) for the first time. The shell structure is made of functionally graded porous graphene platelet reinforced composite (FGP-GPLRC) – one kind of porous material strengthened by graphene platelets (GPLs). Effective material properties of the FGP-GPLRC are determined by the modified Halpin-Tsai micromechanical model and the mixture rule. Four types of porosity distributions and GPL dispersions are considered fully in this study. The governing equations of the shell are derived based on the S-FSDT and classical shell theory, then solved by the well-known Rayleigh-Ritz method and the artificial spring technique. The results show that the S-FSDT can capture well the behaviors of the spherical shell segments. Besides, the best profile of novel FGP-GPLRC is not fixed; the physical parameters, geometric parameters, and material characteristics of the shells need to be investigated fully.Keywords: Free vibrationFGP-GPLRCspherical shell segmentssimple FSDTclassical shell theoryRayleigh-Ritz method Disclosure statementThe authors have no conflicts of interest to disclose.Additional informationFundingThis research is funded by the Thailand Science Research and Innovation Fund Chulalongkorn University (BCG66210019).

Static behaviour of functionally graded plates resting on elastic foundations using neutral surface concept

Van-Loi Nguyen Trần Minh Tú Van-Long Nguyen Quang-Huy Le

Static behaviour of functionally graded plates resting on elastic foundations using neutral surface conceptIn this study, static behaviors of functionally graded plates resting on Winkler-Pasternak elastic foundation using the four-variable refined theory and the physical neutral surface concept is reported.The four-variable refined theory assumes that the transverse shear strain has a parabolic distribution across the plate's thickness, thus, there is no need to use the shear correction factor.The material properties of the plate vary continuously and smoothly according to the thickness direction by a power-law distribution.The geometrical middle surface of the functionally graded plate selected in computations is very popular in the existing literature.By contrast, in this study, the physical neutral surface of the plate is used.Based on the four-variable refined plate theory and the principle of virtual work, the governing equations of the plate are derived.Next, an analytical solution for the functionally graded plate resting on the Winkler-Pasternak elastic foundation is solved using the Navier's procedure.In numerical investigations, a comparison of the static behaviors of the functionally graded plate between several models of displacement field using the physical neutral surface is given, and parametric studies are also presented.

Exact solution for nonlinear static behaviors of functionally graded beams with porosities resting on elastic foundation using neutral surface concept

Proceedings of the Institution of Mechanical Engineers Part C Journal of Mechanical Engineering Science (2021)

Nguyen Van Duc Long Van-Loi Nguyen Trần Minh Tú Duc‐Kien Thai

In this paper, an exact solution for nonlinear static behaviors of functionally graded (FG) beams with porosities resting on the elastic foundation is presented. The FG material properties with porosities are assumed to vary along the thickness of the beam, and two types of porosity distributions are considered. Actually, the geometrical middle surface of the FG beam selected in computations is very popular in the literature. By contrast, in this study, the physical neutral surface of the beam is utilized. Based on the Timoshenko beam theory, von Kármán nonlinear assumption, together with neutral surface concept, the nonlinear governing equations of the FG beam resting on the elastic foundation are derived. By using the physical neutral surface, the nonlinear governing equations have simple forms and can be solved directly. The exact solution for the problem with all immovable and moveable boundary conditions is conducted in detail. Some numerical investigations to show the effects of boundary conditions, material properties, length-to-thickness ratio, elastic foundation coefficients and several types of applied load on nonlinear static bending behaviors of the beam are given.

Vibration Analysis of Rotating Functionally Graded Cylindrical Shells with Orthogonal Stiffeners

Latin American Journal of Solids and Structures (2016)

Trần Minh Tú Van-Loi Nguyen

In this paper, free vibration analysis of rotating functionally graded cylindrical shells with orthogonal stiffeners is presented. Based on Love's first approximation theory and smeared stiffeners technique, the governing equations of motion which take into account the effects of initial hoop tension and also the centrifugal and Coriolis forces due to rotation are derived. The influence of the power law index, the stiffener's height-to-width ratio, the circumferential wave numbers, the shell length-to-radius ratio, and the shell radius-to-thickness ratio on the natural frequencies of the simply supported rotating stiffened functionally graded cylindrical shell are investigated. To validate the present analysis, comparisons are made with those available in the literature for particular cases; very good agreements are achieved.

VIBRATION ANALYSIS OF CROSS-PLY LAMINATED COMPOSITE DOUBLY CURVED SHALLOW SHELL PANELS WITH STIFFENERS

Vietnam Journal of Science and Technology/Science and Technology (2017)

Trinh Anh Tuan Trần Minh Tú Trần Hữu Quốc Van-Loi Nguyen

In this paper, the analytical solution for the cross-ply laminated composite double curved shell panels with stiffeners is presented. Based on the smeared stiffeners technique and the first shear deformation theory (FSDT), the motion equations are derived by applying the Hamilton’s principle. The Navier’s solution for the simply supported boundary condition for all edges is presented. The numerical results are veriﬁed with the known results in the literature. The effects of the number of stiffeners, dimensions of stiffeners, and lamination scheme of cross-ply laminated composite doubly curved shell panels on the natural fundamental frequencies are investigated.
