In this paper the effects of circular and elliptical cutout on the buckling behavior of a sixteen ply quasi-isotropic graphite/epoxy symmetrically laminated rectangular composite plate [0°/+45°/45°/90°]2s, subjected to various linearly varying in-plane compressive loads, numerically. Further, this paper addresses the effects of size of elliptical cutout, orientation of elliptical cutout, plate ...
This paper discusses the use of Distance based optimal designs in the design of experiments (DOE) and artificial neural networks (ANN) in optimizing the stacking sequence for simply supported laminated composite plate under uniformly distributed load (UDL) for minimizing the deflections and stresses. A number of finite element analyses have been carried out using Distance-based optimal design, ...
Abstract In the present paper, fundamental frequency optimization of symmetrically laminated composite plates is studied using the combination of Elitist-Genetic algorithm (E-GA) and finite strip method (FSM). The design variables are the number of layers, the fiber orientation angles, edge conditions and plate length/width ratios. The classical laminated plate theory is used to calculate the n...
Buckling behavior of laminated composite plates subjected to in-plane loads is an important consideration in the preliminary design of aircraft components. The sizing of many structural subcomponents of the aircraft structures is often determined by stability constraints. The objective of the current study is to understand the influence of the length-to-thickness ratio, the aspect ratio, the fi...
in this paper, a closed form solution for bending and free vibration analyses of simply supported rectangular laminated composite plates is presented. the static and free vibration behavior of symmetric and antisymmetric laminates is investigated using a refined first-order shear deformation theory. the winkler–pasternak two-parameter model is employed to express the interaction between the lam...
Stress laminated timber bridge deck technology has been established in Australia since 1991, resulting in the construction of over 40 prototype bridges. This paper presents an overview of the R&D undertaken to implement this technology, involving laboratory testing and field application of plate decks spanning up to 9m and high capacity cellular decks spanning 12m, with the potential to span up...
We use the Eshelby±Stroh formalism to analyze the generalized plane strain quasistatic deformations of an anisotropic, linear elastic laminated plate. The laminate consists of homogeneous laminae of arbitrary thicknesses. Computed results are presented for three sample problems to illustrate the eect of boundary conditions and of the span to height ratio. # 1999 Elsevier Science Ltd. All right...
