Symmetry in Mechanical Engineering: Properties and Applications (Second Edition)

Dear Colleagues,

Symmetry in mechanical engineering refers to the balanced arrangement of components and features in a system or design. Symmetrical properties, such as axial, radial, or planar symmetry, enable the uniform distribution of forces, vibrations, and loads, resulting in improved structural integrity and reduced wear. A symmetrical design often offers greater stability, ease of manufacturing, and cost-effectiveness, and it has diverse applications in mechanical engineering: e.g., in structural engineering, symmetrical shapes and arrangements enhance load-bearing capacity, minimizing stress concentrations; in fluid mechanics, symmetrical profiles reduce drag, enhance flow characteristics, and improve energy efficiency. On the other hand, asymmetry can offer unique advantages to  mechanical systems in specific scenarios: e.g., by introducing asymmetry via variations in material properties, surface textures, or geometry, a specialized thermal behavior could be performed, such as localized heat spreading, directed thermal gradients, or controlled temperature differentials. Therefore, constructing or modifying symmetry could provide properties that enhance the reliability, functionality, and efficiency of mechanical systems, which is an effective approach in mechanical engineering to satisfy the requirements of performance and functions for different applications and under different conditions.

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 250 words) can be sent to the Editorial Office for assessment.

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. Symmetry is an international peer-reviewed open access monthly 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 2400 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.
