TLDR
In this paper, a method for estimating the natural frequencies of composite cantilever plates and for non-dimensionalizing frequency data is developed and demonstrated based on a partial Ritz (Kantorovich) analysis, which reduces the problem to a set of uncoupled ordinary differential equations.About:

Evaluation of in-plane shear modulus of composite laminates using holographic interferometry
TL;DR: Maeda et al. as mentioned in this paper presented a test method for the evaluation of the in-plane shear modu-lus of composite laminates, which is essentially aresonance test on a cantilevered rectangular orthotropic laminate using laser holographic interferometry.

Comparison of frequency deteriiination techniques for cantilevered plates with bencing-torsion coupling
D. Jensen,E. Crawley +1 more
TL;DR: In this paper, various techniques for solution of the variational statement governing vibration of cantilevered composite plates with bending-torsion coupling are compared, including the Rayleigh-Ritz solution, requiring assumed mode shapes in both directions, revealing the fundamental coupling mechanisms affecting the natural mode shapes and frequencies.

Dynamic behavior of composite marine propeller blades
TL;DR: In this paper, the authors provide an assessment of the literature dealing with the use of composite materials in relatively recent applications to marine structures. But the analysis of the behavior of the blade is complex because of the geometry, the effects of the rotation of the propeller, the interaction with the water, and the anisotropic nature of the material.

Improvement of Plate and Shell Finite Elements by Mixed Formulations
S. W. Lee,T. H. H. Plan +1 more
TL;DR: In this article, mixed formulations are introduced as a means for reducing severe constraints in finite-element derivations for plate bending elements to include transverse shear effect and to be applicable also to thin plates.

The Natural Modes of Graphite/Epoxy Cantilever Plates and Shells
TL;DR: The natural frequencies and mode shapes of a number of Graphite/Epoxy and Graphite-Epoxy-Aluminum plates and shells were determined in this article, and the results were compared with those calculated by a finite element analysis.
