“…El-Damatty et al [240] performed thermal analysis of composite chimneys using finite shell elements. Roy et al [241] developed an improved shell element for smart fiber reinforced composite structures under coupled piezothermoelastic loading. Also, Kulikov and Plotinkova [242] constructed a seven parameter geometrically exact shell element to study coupled problem of thermopiezoelectricity in laminated plates and shells.…”

Laminated composite shells are frequently used in various engineering applications including aerospace, mechanical, marine, and automotive engineering. This article reviews the recent literature on the static analysis of composite shells. It follows up with the previous work published by the first author [1-4] and it is a continuation of another recent article that focused on the dynamics of composite shells [3]. This paper reviews most of the research done in recent years (2000-2010) on the static and buckling behavior (including postbuckling) of composite shells. This review is conducted with an emphasis on the analysis performed (static, buckling, postbuckling, and others), complicating effects in both material (e.g. piezoelectric) and structure (e.g. stiffened shells), and the various shell geometries (cylindrical, conical, spherical and others). Attention is also given to the theory being applied (thin, thick, 3D, nonlinear …). However, more details regarding the theories have been described in previous work [1,3]

“…The actuator voltage was kept within the limit in order to maximize the damping ratio. Further Roy et al 29 proposed an improved GA for composite shell structures under combined effect of mechanical and thermal environment. The real-coded GA was incorporated in order to maximize the damping while keeping the actuator voltages within allowable limit.…”

The current article deals with finite element (FE)-and genetic algorithm (GA)-based vibration energy harvesting from a tapered piezolaminated cantilever beam. Euler-Bernoulli beam theory is used for modeling the various cross sections of the beam. The governing equation of motion is derived by using the Hamilton's principle. Two noded beam elements with two degrees of freedom at each node have been considered in order to solve the governing equation. The effect of structural damping has also been incorporated in the FE model. An electric interface is assumed to be connected to measure the voltage and output power in piezoelectric patch due to charge accumulation caused by vibration. The effects of taper (both in the width and height directions) on output power for three cases of shape variation (such as linear, parabolic and cubic) along with frequency and voltage are analyzed. A real-coded genetic algorithm-based constrained (such as ultimate stress and breakdown voltage) optimization technique has been formulated to determine the best possible design variables for optimal harvesting power. A comparative study is also carried out for output power by varying the cross section of the beam, and genetic algorithm-based optimization scheme shows the better results than that of available conventional trial and error methods.

“…Noticeably, the hourglass stabilization is also formulated in such a way, that neither volumetric nor transversal shear locking occur. The accurate determination of stress distributions in thickness direction for laminated layered composites has been recently investigated in [32] using an improved shell formulation and in [33,34] based on the solid-shell concept. For a more elaborate literature overview the interested reader is referred to the review papers [35][36][37] and the references therein.…”
