Free Vibration of Laminated Composite Plate with Square Cut-outs: A Numerical and Experimental Analysis
Main Article Content
Abstract
In the current research, the hand lay-up method has been employed to produce laminated composite plates. Bidirectional glass fibers and epoxy resin have been chosen as reinforcement and matrix for the fabrication of laminated composite plates respectively. The design parameters viz. aspect ratio, position of cut out, cut out ratio, number of layers, and ply orientations in various end conditions are considered for the experimental dynamics test of the plate. The vibrational analysis of the composite plate having cut-outs has been performed numerically using ANSYS software. The changes in natural frequency concerning the considered design parameters have been analyzed and discussed for different boundary conditions. The experimental results are checked with the numerical simulation results attained through ANSYS to validate the current research.

Journal author rights
In order for Romanian Journal of Acoustics and Vibration to publish and disseminate research articles, we need publishing rights. This is determined by a publishing agreement between the author and Romanian Journal of Acoustics and Vibration. This agreement deals with the transfer or license of the copyright to Romanian Journal of Acoustics and Vibration and authors retain significant rights to use and share their own published articles. Romanian Journal of Acoustics and Vibration supports the need for authors to share, disseminate and maximize the impact of their research and these rights, in Romanian Journal of Acoustics and Vibration proprietary are defined below:
For subscription articles:
Authors transfer copyright to the publisher as part of a journal publishing agreement, but have the right to: Share their article for personal use (manuscript version); retain patent, trademark and other intellectual property rights (including research data); proper attribution and credit for the published work.
For open access articles:
Authors sign an exclusive license agreement, where authors have copyright but license exclusive rights in their article to the publisher. In this case authors have the right to: share their article in the same ways permitted to third parties under the relevant user license; retain patent, trademark and other intellectual property rights (including research data); proper attribution and credit for the published work.
Rights granted to Romanian Journal of Acoustics and Vibration
For both subscription and open access articles, published in proprietary titles, Romanian Journal of Acoustics and Vibration is granted the following rights:
- The exclusive right to publish and distribute an article, and to grant rights to others, including for commercial purposes;
- For open access articles, Romanian Journal of Acoustics and Vibration will apply the relevant third party user licence (Open access licencses) where Romanian Journal of Acoustics and Vibration publishes the article on its online platforms;
- The right to provide the article in all forms and media so the article can be used on the latest technology even after publication;
- The authority to enforce the rights in the article, on behalf of an author, against third parties, for example in the case of plagiarism or copyright infringement.
