In this paper, the optimum weight and cost of a laminated composite plate is seeked, while it undergoes the heaviest load prior to a complete failure. Various failure criteria are defined for such structures in the literature. In this work, the TsaiHill theory is used as the failure criterion. The theory of analysis was based on the Classical Lamination Theory (CLT). A newly type of Genetic Alg...

Following previous work of [Dong, El-Gizawy, Juhany, Atluri (2014)], a simple locking-alleviated 3D 8-node mixed-collocation C0 finite element (denoted as CEH8) is developed in this study, for the modeling of functionally-graded or laminated thick-section composite plates and shells, without using higher-order or layer-wise zig-zag plate and shell theories which are widely popularized in the cu...

This paper describes the design optimization of ferrocement-laminated plate made up of reinforcing steel wire mesh(es) and cement mortar. For the improvement of the designing process, the plate is modeled as a multi-layer medium, dividing the ferrocement plate into layers of mortar and ferrocement. The mortar layers are assumed to be isotropic in nature and the ferrocement layers are assumed to...

A laminated composite plate element with an interface description is developed using the finite element approach to investigate the bending performance of two-layer cross-ply laminated composite plates in presence of a diagonally perturbed localized interfacial degeneration between laminae. The stiffness of the laminate is expressed through the assembly of the stiffnesses of lamina sub-elements...

Abstract Composite materials are widely used in aerospace industries due to their light weight, strength, and various other desired properties. However, they susceptible defects occurring during the manufacturing process or service. Typical include porosity, wrinkles, delamination. Nondestructive means of detection at any stage great importance ensure quality safety composite structures. A noni...

This study presents the dynamic and buckling analysis of laminated composite thin arch plate frame structures employing Classical Plate Theory with Finite Element Analysis. For this purpose, The effects radius curvature, aspect ratio, stacking order such on first ten natural frequencies, mode shapes, critical load, unstable regions are investigated. Besides, two-bay curved structure is In to pe...

Composite structures are extensively applied because of their high specific stiffness-to-weight ratios and other advantages. In various scenarios, composite elastically coupled usually exposed to a nonuniform thermal environment. This paper presents numerical simulation studies on the vibroacoustic characteristics laminated plate with elastic supports subjected local temperature. The stiffness ...
