Magnetostrictive Composite Materials

Dear Colleagues,

The interest in magnetostrictive composite materials has steadily increased in recent years. The reason for this success is that the new generation of composite material systems show special functionalities: Sensing, actuation, structural health monitoring, vibration control, energy harvesting. Magnetostrictive composite materials, including electromagnetic (ME) composites and magneto-sensitive elastomers, are used in the realization of smart materials and structures. The constitutive behavior of these composite materials couples their mechanical response with other physical fields. In magnetostrictive materials, the magnetic behavior is coupled with the mechanical one due to the direct magnetostrictive effect and inverse (Villari) effect.

The integration of magnetostrictive (active) materials into the traditional (passive) ones is a key aspect in the material and structural behavior, and this integration can occur at different scales and in different ways. At the micromechanical level, particles, fibers, and thin films of magnetostrictive materials can be arranged irregularly or regularly in passive ones. At a macroscopic level, the arrangement of active and passive parts can assume the shape of a bar, plate or shell. These give an idea of the motivations that drive the research effort in modelling and simulation, fabrication and characterization, reliability and durability of the magnetostrictive composite materials, and the reason why this is a very challenging open research field.

This Special Issue covers a very wide and varied range of subject areas that fall under its title-theme, and all aspects (theoretical, computational, experimental studies and/or industrial applications) of magnetostrictive composite materials from state-of-the-art fundamental research to applied research and applications in emerging technologies.

It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

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. 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.
