Special Issue Information

Dear Colleagues,

After our successful first two editions of the Special Issue “Plastic Deformation, Strengthening and Toughening of Advanced Metallic Materials”, we have decided to create a 3rd edition to collect and publish state-of-the-art research in the field of plastic deformation, strengthening and toughening of metallic materials.

Metallic structure materials have been gaining widespread industrial applications, owing to their excellent properties. Strong metals are substantially desired in lightweight and energy-efficient industrial designs, such as in extensive applications of high-strength steels and aluminium (Al) alloys in automobiles, trains, and planes. In most industrial alloy production and modern alloy design strategies, multiple obstacle families (for instance, solid solutions, particles and grain boundaries) and dislocations are employed to increase the strength. In recent years, numerous efforts have been contributed to processing high-strength metallic materials with good ductility or toughness. For such advanced alloys, the mechanisms of strengthening and toughening, as well as their plastic deformation mechanisms related dislocations evolutions, are still under debate.

In this Special Issue, we welcome the submission of original research articles, communications and reviews concerning the plastic deformation, strengthening and toughening of advanced metallic materials. Contributions demonstrating experiments, simulations and modelling related to the above subject are welcomed.

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.

Although the cyclic bending behavior of circular and elliptical steel tubes has been widely studied, the combined effects of major-to-minor axis length ratio and curvature ratio on the deformation characteristics and buckling life of galvanized steel elliptical tubes remain insufficiently understood. This study experimentally investigates the cyclic bending response and failure behavior of galvanized steel elliptical tubes with major-to-minor axis length ratios of 1.5, 2.0, 2.5, and 3.0 under curvature ratios of −1, −0.5, and 0. The curvature ratio is defined as the minimum controlled curvature divided by the maximum controlled curvature. Buckling is defined as the cycle at which a pronounced 20% drop in peak bending moment is observed. The response is characterized by moment (N⋅m)–curvature (m−1) hysteresis and minor-axis variation with curvature, while failure is evaluated using the relationship between curvature range and number of cycles to buckling. The results show that stable elastoplastic hysteresis loops develop for all curvature ratios, with slight cyclic relaxation observed at curvature ratios of −0.5 and 0. Increasing the axis length ratio slightly reduces the peak moment under a fixed curvature ratio. Minor-axis variation increases progressively with cycle number, exhibiting serrated curves at an axis ratio of 1.5 and butterfly-shaped curves at higher axis ratios. Symmetric behavior is observed at a curvature ratio of −1, whereas asymmetric responses occur at −0.5 and 0. The failure results indicate that larger curvature ranges and higher axis length ratios reduce the number of cycles to buckling, while curvature ratios closer to −1 enhance buckling life. On a log–log scale, the relationship between curvature range (m−1) and number of cycles to buckling becomes linear. A theoretical model is proposed and shows good agreement with the experimental results. Full article
