A simple rectangular element for twodimensional analysis of laminated composites. [J D Whitcomb; Langley Research Center.]. A simple rectangular finite element was developed for twodimensional analysis of laminated composite materials.
The rectangular laminated composite element eliminates the need to add elements to a model simply to account for the material properties of various laminae.
This is particularly advantageous for thick laminates with many : J. Whitcomb. To this end, a cross sectional finite element stress analysis was applied by Sen and Fish [1, 2] to determine the stresses in glassepoxy thirtytwoply flexbeam laminates under torsion and combined tensiontorsion loads.
The largest mesh in the finite element analysis consisted of 7, elements w degrees of freedom. An evaluation of the element is conducted with respect to the accuracy obtained in the bending of laminated anistropic rectangular plates with different lamination schemes, loadings, and boundary.
Choudhary and Tungikar () analyzed the geometrically nonlinear behavior of laminated composite plates using the finite element analysis.

Among the various aspects of the structural performance of elements made of composite materials, rectangular laminated plates has drawn much holes, which ensure pipelines or wires can pass through it, are inevitable in the design progress and bring problem of stress. A review of the recent development of the finite element analysis for laminated composite plates from is presented in this paper.
The literature review is devoted to the recently developed. Consider, a rectangular, thin laminated composite plate of length a, width b and thickness h as shown in Fig The plate consists of a laminate having n number of laminae with different materials, fibre orientations and thicknesses.
The ninenoded quadratic Lagrangian twodimensional element is used with five and nine degrees of freedom per node. The accuracy of the formulation is verified by analyzing sample problems available in literature.
Numerical results are presented in nondimensional form for symmetric, antisymmetric, and crossply laminates, both thick and thin. Analysis of laminated composite shell structures by finite element method pectively. This implies an approximation that all layers rotate through the same angle, a better approach would have been to take separate normal rotations for each layer, but this will involve large number of degrees of freedom and consequently limit the usefulness.

The full text of this article hosted at is unavailable due to technical difficulties. In this paper a refined higherorder shear deformation theory for the instability finite element analysis of fibre reinforced shell like composite structures is developed.
A higher order shear deformation theory allows parabolic description of the transverse shear stresses and therefore the shear correction factors of the usual shear deformation theory are not required.
The proposed elements, namely NSMITC3, show good accuracy and convergence as compared to other plate elements when employed to analyze laminated composite plates.

This book intend to supply readers with some MATLAB codes for ﬁnite element analysis of solids and structures. After a short introduction to MATLAB, the book illustrates the ﬁnite element implementation of some problems by simple scripts and functions. The following problems are discussed: • Discrete systems, such as springs and bars.

The use of bistable unsymmetric crossply laminates for morphing application has received growing attention in the last few years. So far, most studies use large rectangular piezoelectric Macro Fiber Composite (MFC) patches bonded at the center of the laminate to induce snapthrough.
