Special Issue Information
Dear Colleagues,
Structural vibration control has long been one of the fastest-growing and most challenging fields in civil, mechanical and aerospace engineering. Since the early days of vibration control research, a key scientific issue has been how to leverage symmetry or asymmetry in structural dynamics to design effective control strategies—such symmetry is widely present in the dynamic characteristics of engineering systems. By exploiting this symmetry, researchers can achieve more efficient vibration suppression, energy dissipation or isolation in real-world environments. Although recent research trends have shifted toward intelligent control, nonlinear control and metamaterial designs, the central role of symmetry and asymmetry has not diminished. On the contrary, as engineering structures become larger, lighter and more complex, many new practical problems continue to emerge. While pursuing robust solutions to these challenges, we hope to see deeper exploitation of symmetry and asymmetry—such as simplified modal analysis using symmetric layouts, directional energy dissipation via asymmetric dampers or the advantages of bio-inspired asymmetric structures for broadband vibration isolation—leading to improved control performance.
Against this background, this Special Issue aims to highlight recent academic advances or innovative applications in structural vibration control that emphasize the role of symmetry and asymmetry. The concept of symmetry/asymmetry plays an important role in the co-design of passive and active control, asymmetric stiffness configurations in nonlinear energy sinks, asymmetric circuit design in piezoelectric or electromagnetic energy harvesting systems, symmetric/asymmetric support strategies in rotating machinery and symmetry-breaking wave control based on metamaterials.

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-anonymized 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.
