Abstract Rainbow trapping is of great significance for frequency-based wave splitting and broadband attenuation. By recognizing the deficiency prevailing gradient rainbow reflection devices in terms energy concentration vibration isolation, we design a new topological device by introducing protected interface mode (TPIM) into device. Therefore, beam composed homogenous rested on an alternate foundation constructed. Using theoretical numerical analysis, perform unit-cell band structure...
In this paper, an analytical Hamiltonian-based model for the dynamic analysis of rectangular nanoplates is proposed using Kirchhoff plate theory and Eringen’s nonlocal theory. a symplectic space, problem reduced to solving unified Hamiltonian dual equation formed by total unknown vector consisting displacements, rotation angles, bending moments generalized shear forces. The exact solutions free vibration, buckling steady state forced vibration are established eigenvalue expansion...
We studied the characteristics of a phononic crystal which consists hollow pillars mounted on surface semi-infinite substrate. In this study, existence waves whispering gallery modes referred as localized cavity at subwavelength frequency spectrum is reported. The interaction with induce and by tuning inner radius these confined can be adjusted/tuned inside bandgap region, thus introducing new applications for based crystals acoustic metamaterial devices. These possess high-q narrow passband...
Para-xylene (PX) is an important material for the production of polyester fibers and resins; it widely used in fuel medical fields. To alleviate low strength unsatisfactory mass-transfer performance conventional catalysts during xylene isomerization, a combined-structure catalyst fabricated using three-dimensional (3D) printing technology. In this study, ink formulation preparation method suitable 3D designed, wet ball-milling process adopted to improve stability printing. The structured are...
Exact solutions for the torsional bifurcation buckling of functionally graded (FG) multilayer graphene platelet reinforced composite (GPLRC) cylindrical shells are obtained. Five types platelets (GPLs) distributions considered, and a slope factor is introduced to adjust distribution profile GPLs. Within framework Donnell’s shell theory with aid symplectic mathematics, set lower-order Hamiltonian canonical equations established solved analytically. Consequently, critical loads corresponding...
An accurate nonlinear buckling model for functional graded multilayer hybrid composites cylindrical shells under combined loads is proposed. A two-steps micromechanical approach including Halpin-Tsai and Mori-Tanaka method employed to obtain the effective material properties of composites. unified shell theory Donnell's theory, first-order shear deformation high-order are adopted derive governing equations. The axisymmetric pre-buckling taken into consideration in solution procedure. Highly...
An accurate buckling response analysis for functionally graded graphene platelet (GPL) reinforced piezoelectric cylindrical nanoshells subject to thermo-electro-mechanical loadings is presented by a rigorous symplectic expansion approach. Three types of GPL patterns are considered, and the modified Halpin–Tsai model employed determine their effective material properties. By using Eringen’s nonlocal stress theory Reissner’s shell theory, new governing equations established in Hamiltonian...
