“…Shen and Xiang [27] Present To simplify the manufacturing process, graphene directions of ring and stringer stiffener systems are related together. [37] If the graphene of the ring stiffener system is arranged in the zigzag direction, the graphene of the stringer stiffener system is arranged in the armchair direction, and contrary, in the corresponding layers. The stiffeners in circumferential and longitudinal directions are made with the same number of GRC layers, thickness and volume fraction of graphene of each layer, respectively.…”

The main aim of this article is to establish an analytical approach on the torsional postbuckling for functionally graded graphene‐reinforced composite (FG‐GRC) laminated circular cylindrical shells stiffened by FG‐GRC laminated stiffener system in thermal environment and subjected to torsion loads. The polymer matrixes of shell skin and stiffeners are reinforced by graphene with two graphene reinforcement directions, namely, zigzag and armchair directions. The anisotropic smeared stiffener technique for FG‐GRC stiffener system is used, and the governing equations are established based on the Donnell shell theory with von Kármán–Donnell‐type geometrical nonlinearity and the Airy's stress function. A three‐state solution of deflection is chosen and Galerkin's method is applied, the explicit forms of critical buckling torsion and expression of load‐deflection postbuckling curves relation are obtained. The effects of graphene‐reinforced composite laminated stiffeners, uniformly distributed temperature, the volume fraction of graphene of stiffened shell on the nonlinear torsional buckling behavior are numerically investigated.

“…The eccentrically stiffened structure is the reinforced option with the advantages of lightweight and high capacity properties, and it is very popular in engineering designs. The cylindrical shells made by basic, classical composite and advanced composite material stiffened by stiffener system were mentioned and modeled in many researches [18][19][20][21][22][23][24][25][26]. The isotropic and laminated cylindrical shells stiffened by isotropic stiffeners were modeled by using classical homogenization stiffener technique with different approaches [18][19][20][21].…”

Nonlinear buckling and postbuckling of longitudinally compressed carbon nanotube-reinforced (CNTR) cylindrical shells stiffened by longitudinal or circumferential CNTR stiffeners in thermal environments surrounded by elastic medium are presented in the present study. Five linear distributions of CNT are considered for the shell-stiffener structure system and they are modeled by innovation homogenization technique for CNTR stiffeners. Based on the classical Donnell thin shell theory with von Karman's nonlinearities and the Galerkin procedure, the governing equations can be built to analyze the critical buckling compression and postbuckling compression-deflection and compression-shortening behavior. The noticeable effects of volume fraction of CNTs, shell-foundation interaction stiffnesses, uniformly distributed temperature, and geometric properties of stiffened cylindrical shells on the critical buckling compression and compression-deflection and compression-shortening postbuckling behaviors of stiffened CNTR cylindrical shells are obtained and remarked in numerical examinations. INTRODUCTIONCarbon Nanotube (CNT) reinforced composite is known to be an advanced composite with high-performance material. The CNTs with the high aspect ratio, low density, exceptional, electro-thermo-mechanical properties can be used to enhance the electrical thermal, and mechanical properties of basic materials. By reinforcing the CNTs for the same directions into the isotropic material, Shen [1, 2], created the special type of CNT-reinforced (CNTR) composite with the functionally graded (FD) volume fraction of CNT in the thickness direction of shells. The longitudinally compressed CNTR cylindrical shells are the outstanding structures that were studied with different thermo-mechanically linear and nonlinear problems such as static buckling and postbuckling behaviors [1-3], combined loads of axial compression and external pressure [4], free and forced vibration responses [5][6][7], and dynamic stability [8][9][10][11][12]. The more complex load types as dynamical seismic loads applied for CNTR cylindrical shells were also considered and analyzed [13,14] taking into account the moisture and hygrothermal effects. An ideal for a CNTR composite material with the two-directional reinforcements of CNTs was presented [15,16] and nonlinear buckling of cylindrical

Buckling performance of co‐cured and stiffened composite structure with embedded multilayer damping membranes

This research aims to explore the buckling performance of a co‐cured and stiffened composite structure with embedded multilayer damping membranes (CSCSEMDM) under static load. A buckling model of this structure is established theoretically by using the principle of minimum potential energy and first‐order shear deformation theory. Then, the governing equation of the structure is obtained. The critical buckling load of the structure is solved, and the finite element method is used to verify the correctness of the theoretical model and theoretical methods. Finally, the effects of various parameters on the critical buckling load are discussed on the basis of the validated model.
