TL;DR: In this paper, a layerwise optimization approach is proposed to optimize vibration behavior for the maximum natural frequency of laminated composite plates, which is based on the physical consideration that the outer layer has more stiffening effect than the inner layer in the bending of plates and is more influential in determining the natural frequency.

TL;DR: In this article, a multi-objective optimization approach for fibrous composite plates with curvilinear fibers is proposed, where the non-dominated sorting genetic algorithm (NSGA-II) is used to obtain Pareto-optimum solutions.

TL;DR: In this paper, the problem of finding the natural frequencies of free vibration of a simply supported circular plate has a straightforward solution, but very few numerical results are available in the literature.

TL;DR: In this paper, the Ritz method is used for angle-ply plates, and good convergence is obtained by using 144 terms in the double-sine series for the displacement function, and tabulated results are presented for the first eight non-dimensional frequencies of square and rectangular (a b = 1,2 and 0·5 ) plates made of E-glass/epoxy, boron/epoxide, and graphite-epoxy materials, for different numbers of layers and for varying fiber orientation angles.

TL;DR: In this paper, the critical buckling loads of simply supported, rectangular, laminated composite plates subjected to five types of loading conditions: (1) uniaxial, (2) hydrostatic biaxials, (3) compression-tension biaaxial,(4) positive shear and (5) negative shear.
