Residual Stress Analysis of Welded Structure

Dear Colleagues,

As the usage of large-scale, high-strength metallic structures increases significantly in various civil engineering constructions and other areas, higher standards and assessments are required to ensure their structural integrity and performance. This is critical when welding heavy-section or very thick steel plate and pipes because most welded structures contain significant levels of residual stresses, which can lead to the abrupt fracture and fatigue-elated failure. Furthermore, the through-thickness variations of residual stresses are important in large, thick welds due to the completely different distributions of residual stresses inside the welded structure from accumulated heat input. Although there are intrinsic limitations and difficulties in the determination of the residual stresses in heavy-section welded structures, a few promising methods have been applied destructively, nondestructively, or complementarily.

I invite you to send scientifically valuable articles for a Special Issue of Metals entitled "Residual Stress Analysis of Welded Structure". Its scope is very wide and covers all issues of welding including residual measurement, welding processes, the effect of welding residual stress on fracture safety, and numerical analyses. The purpose of this Special Issue is to present methodologies for improving the safety of various structures through a clear examination of the welding residual stress, and as such, submitted articles should concern the issues of the measurement method and the FE-analysis of the welding residual stress. In addition, research on welding residual stress, which is considered in the evaluation of fracture toughness and the safety of welded structures, is also welcome. Given the quality of Metals, we are confident that this journal is the ideal place to present your research to the world.

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. 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.
