Additively Manufactured Mechanical Metamaterials: Design, Analysis, and Applications

Dear Colleagues,

The design of mechanical metamaterials often makes use of cellular and lattice patterns. The right tuning of these architectures via geometric and dimensional parameter adjustment allows the designer to produce topologies with tailored mechanical properties. Hence, architected mechanical metamaterials appear as a promising option for various applications, e.g., lightweight structures, energy storage, biomedical, and vibration and noise control, among others.

Mechanical metamaterials, also known as architected cellular materials, are not new. They can be found in nature as integral parts of honeycombs, wood, and bone. However, the advent of additive manufacturing technologies has indeed enabled growth in the design and understanding of such porous media. This is attributed to the design freedom enabled by additive fabrication processes. Additive manufacturing facilitates the fabrication of complex geometries which are often demanded by mechanical metamaterials. A wide range of geometrical and structural elements could be used to build up cellular structures, prompting them to be additively manufactured. This Special Issue aims to collect recent developments in the areas related to mechanical metamaterials fabricated with additive manufacturing.

Submissions are welcome that cover, but are not limited to, the aspects of:

• Design of mechanical metamaterials.
• Design for additive manufacturing.
• Mechanical properties of cellular and lattice materials.
• Additive manufacturing of architected materials.
• Experimental characterization of the mechanical properties of cellular materials.
• Computational approaches to characterize structure–property relation.
• Other cutting-edge research on understanding the structure/manufacturing–property relation of this architected media.
• Other applications of metamaterials, e.g., vibration and damping control and noise attenuation.

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. Applied Sciences 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 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.
