Special Issue Information

Dear Colleagues,

In the past several decades, shape memory alloys (SMAs) have been at the forefront of material research. Owing to their excellent super-elasticity and shape memory effects resulting from their solid–solid thermo-elastic martensite transformation as well as their strong biological compatibility, SMAs have been used for a wide variety of applications in various fields, such as biomedicine, microelectromechanical systems, aerospace, civil engineering, etc. Currently, the most important problems with SMAs include (1) how to improve the basic thermo-mechanical properties of the material; (2) how to understand the underlying physical mechanism of super-elasticity and the shape memory effect; (3) how to develop theoretical models in different spatial and time scales; and (4) how to design SMA-based devices and structures for use in engineering applications.

This Special Issue, titled “Shape memory alloys: material, structure, modeling and application”, will focus on the preparation, characterization, modeling, and application for SMAs and their structures. We invite the submission of research articles, communications, and reviews on topics including but not limited to the following:

  • Preparation and performance optimization of SMAs;
  • Characterization of thermos-mechanical properties of materials and structures of SMAs;
  • Development of multi-field coupled constitutive models, multi-scale modeling, and fatigue failure assessment for SMAs;
  • Intelligence and structural applications of SMAs.

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.

By assimilating shape memory alloys with mathematical multifractal-type objects, a theoretical model based on Scale Relativity Theory in the form of The Multifractal Theory of Motion, in order to explain the mechanical behavior of such material, is proposed. The model is validated by analyzing the mechanical behavior of Cu–Al–Zn shape memory alloy with various chemical compositions. More precisely, the multifractal tunnel effect can “mime” the mechanical hysteresis of such a material, a situation in which a direct correspondence for several mechanical properties of Cu–Al–Zn is highlighted (the chemical composition can be correlated with the shapes of the curves controlled through the multifractality degree, while the areas delimited by the same curves can be correlated with the multifractal specific potential, as a measure of the mechanical memory degree).
