Special Issue Information

Dear Colleagues,

Modern ship design focused on pro-ecological solutions follows a comprehensive approach to all elements of construction and equipment, which must meet a number of stringent requirements in the fields of safety, ecology and functionality. The materials used require a combination of low weight, flame retardancy, high strength, high stiffness, and good fatigue resistance. One of the key aspects is reducing the weights of the structural elements and equipment of passenger vessels such as cruise ships, yachts, passenger ferries, in which the share of crew and passengers relative to the size of the vessel is relatively high. Then, reduced equipment weight means reduced energy consumption, translating into increased efficiency and reduced pollutant emissions. The lower weight of the equipment means that the standard displacement of the vessel increases.

This Special Issue focuses on composite materials used in the maritime industry. It will highlight recent progress in the study of properties and applications of these materials, covering both experimental characterization and modeling methods. We invite researchers to share their latest investigations in the form of research articles and reviews.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Modeling the dynamic properties of wood and wood-based composites is a challenging task due to naturally growing structure and moisture-dependent material properties. This paper presents the finite element modeling of plywood panels’ dynamic properties. Two panels differing in thickness were analyzed: (i) 18 mm and (ii) 27 mm. The developed models consisted of individual layers of wood, which were discretized using three-dimensional finite elements formulated using an orthotropic material model. The models were subjected to an updating procedure based on experimentally determined frequency response functions. As a result of a model updating relative errors for natural frequencies obtained numerically and experimentally were not exceeding 2.0%, on average 0.7% for 18 mm thick panel and not exceeding 2.6%, on average 1.5% for 27 mm thick panel. To prove the utility of the method and at the same time to validate it, a model of a cabinet was built, which was then subjected to experimental verification. In this case, average relative differences for natural frequencies of 6.6% were obtained. Full article
