Special Issue Information

Dear Colleagues,

As the use 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 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 for you to present your research to the world.

For large ships and offshore vessels, structural safety is verified through whole-ship analysis using commercial software. In the case of general oil tankers, classification rules for structural strength evaluation are uniformly applied. Structural strength evaluation is mainly divided into the cargo hold, fore-end, and aft-end parts. For the structural design of a cargo ship, it is important to calculate the design load and determine the thickness and size of the structural member. Structural FEA (Finite Element Analysis) is performed on only the cargo hold range as recommended by the CSR (Common Structure Rule). There is no FE analysis recommendation for either the aft- or the fore-end area. Therefore, structural safety is carried out based on existing design experience and engineer judgment. With previous approaches, it is difficult to clarify the safety of the aft-end part according to external loads such as hull girder load and local pressure. Recently, local buckling damage cases have investigated the aft-end of the shuttle tanker. Although this is a good example, it can be recognized that it is necessary to improve the accuracy of prediction when estimating the structural safety at the aft-end part. In this study, a novel FE-based evaluation methodology about buckling damage is proposed. In order to conduct a structural strength verification based on FE analysis modeling, reasonable solutions for load conditions, boundary conditions, modeling methods, and evaluation criteria are presented. This result is expected to be helpful in examining the structural strength of the aft-end part of similar carriers in the future. Full article
