Special Issue Information
Dear Colleagues,
Stretch bending is as a critical forming technology in the manufacturing of steel sheet components, widely applied in high-end industries such as aerospace (aircraft frame structures), automotive (body components), and architectural systems (curtain walls). Despite its technological importance, the process imposes complex multi-axial stress states and cyclic plastic deformation on the material, often resulting in microstructural damage accumulation. This damage can significantly accelerate fatigue crack initiation and lead to unexpected fracture failures, thereby compromising the safety, durability, and performance of structural components.
This Special Issue aims to address key scientific issues and technical challenges associated with fatigue failure in steel sheets during stretch bending. The scope of research includes, but is not limited to: (1) Damage evolution mechanisms and fracture criteria of steels under multi-field coupling conditions; (2) The effects of process parameters (e.g., tensile force, bending radius, forming speed) on material fatigue performance; (3) Correlation studies between microstructural evolution and macroscopic mechanical properties; and (4) Machine learning-based approaches for forming process optimization and life prediction.
We particularly welcome original research and review papers that incorporate advanced experimental techniques, high-resolution material characterization, and multi-scale modeling strategies. Contributions from researchers and practitioners in materials science, mechanical engineering, and related fields are highly encouraged to collectively advance the development of this important domain.

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. Metals is an international peer-reviewed open access monthly 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.
