Special Issue Information
Dear Colleagues,
In recent years, much progress has been made on the development of aerospace materials for structural applications. Alloys, such as Al-based alloys, have been developed for the aerospace industry with outstanding advantages. Composite materials have thus started to take on more and more important roles in aircrafts; however, these still face some major issues, such as delamination. Functionally graded materials (FGMs) have been conceived to overcome this limitation. In space applications, high operating temperatures are imposed to couple materials with very different properties; FGMs are characterized by a functional variation in the composition of the material properties along the thickness that reduce the interlaminar discontinuities which are the main cause of delamination.
On the other hand, smart materials are gaining importance continuously in the aerospace industry because of their unique features, such as self-sensing, self-adaptability, memory capabilities, and manifold functions. Finally, a new research field has emerged in the last decade to study metamaterials. These are made from assemblies of multiple elements, and their properties are beyond those of their constituent materials. Several types of metamaterials can be found; among these, acoustic metamaterials are attracting aerospace researchers for the developement of lightweight acoustic insulation treatments.
Classical models cannot be clearly employed in the analysis of all these materials. In most cases, researchers have to resort to classical finite element models based on very fine 3D meshes encountering the following main drawbacks: high computational cost, limited multifield capabilities, and difficulty in coupling the micro- and macroscales in aerospace simulations. Accurate and efficient mathematical models have yet to be implemented.
This Special Issue focuses on the following topics: (1) recent advances in the development of aerospace materials, (2) challenges faced by recent aerospace materials, and (3) advances in modelling of innovative aerospace materials.

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.
