TL;DR: In this article, the effects of cutout on the load bearing capacity and stress concentration of flat infinite plates subjected to a uniaxial tension load were investigated. And the results indicated that the stress concentration factor of perforated plates can be significantly changed by using proper cutout shape, bluntness and orientation.

TL;DR: In this article, the effect of cutout geometry (circular, square, or special cutouts), material properties (isotropic and orthotropic), fiber angles, and cutout curvature are considered.

TL;DR: In this paper, the authors describe the establishment of similarity conditions between two structural systems, which provide the relationship between a scale model and its prototype, and can be used to predict the behavior of the prototype by extrapolating the experimental data of the corresponding small scale model.

TL;DR: In this paper, an analytical investigation was undertaken to show how and to what extent similitude theory can be applied in the design of scaled-down models and the necessary similarity conditions, referred to herein as scaling laws, pertaining to free vibrations of laminated plates are derived.

TL;DR: In this paper, the authors reviewed most of the studies carried out from 2000 on optimizing composite structures by representing a classification based on the type of structures and highlighted important parameters of these optimization approaches namely objective functions, design variables, constraints and the applied algorithms.

TL;DR: In this paper, the authors review most of the research done in recent years (1989-2012) on the vibration analysis of composite beams, with emphasis given to the theory being applied (thin, thick, layerwise), methods for solving equations (finite element analysis, differential transform and others) experimental methods, smart beams (piezoelectric or shape memory), complicating effects in both material and structure, and other areas that have been considered in research.

TL;DR: In this article, the authors reviewed the developments in the methodologies used to create reduced scale models as a design tool, including those based in the use of: dimensional analysis, differential equations and energetic methods.
