Free vibration of composite laminated plate with complicated cutout

Multilayer Viscoelastic Media with Interface Quality Using Pseudo Stroh-Formalism: Application to Local Materials

“…Several types of these structures have been studied among which we have double-glazing, perforated structures, and many others [2]. The approaches to study these structures are various: Impedance approaches, transfer matrix [3], Debye series decomposition method, and the stiffness matrix method [4]. These different approaches can be used to determine properties such as reflection, transmission, transmission loss and absorption.…”

Free vibration optimization of a sandwich structure with a hybrid composite grid core

“…Although numerous studies have focused on optimizing sandwich structures, none of the published research has simultaneously addressed the geometric variables of the ribs, rotation angle of the grid core, and selection of the type of the applied composite for each group of stiffeners in a sandwich structure with a grid core. [22][23][24][25][26][27][28] Accordingly, this research focuses on the vibration behavior of a sandwich structure with an orthotropic grid core and stiffeners that can take an I-shaped cross-section. The skins are considered to be made of identical thin composite materials.…”

Sound transmission loss of double-walled sandwich cross-ply layered magneto-electro-elastic plates under thermal environment

“…He et al 20 studied the effects of the damping ratio, shape, and frequency of delaminated composite plates and indicated that with increasing the delamination percentage, the modal damping ratio meaningfully increases. Hachemi and Hamza-Cherif 21 proposed a numerical solution based on hierarchical finite element formulation for investigating the free vibration response of a composite laminated plate. Sharma et al 22 carried out the static and dynamic responses of the laminated composite plate with piezoelectric layers employing FEM.…”
