Welding sequence effects on residual stress distribution in offshore wind monopile structures
Fracture and Structural Integrity, 2015 Residual stresses are often inevitably introduced into the material during the fabrication processes, such as welding, and are known to have significant effects on the subsequent fatigue crack growth behavior of welded structures.

Carbon Energy, EarlyView.The double‐bond phenomenon enables dual energy band mechanisms that enhance the efficiency of seawater splitting. Atomic interactions at the GO/GaN interface encompass various configurations, such as van der Waals interactions, covalent interactions, type‐II and Z‐scheme alignments, and chloride‐ion repulsion.

Deep Underground Science and Engineering, EarlyView.This research study employs analysis system (ANSYS) fluid–structure interaction simulations to investigate the generation and attenuation of vibration signals resulting from freezing pipe fractures in artificial ground freezing projects. By evaluating key variables—including frozen soil elastic modulus, brine inlet pressure, and external pipe pressure ...

Deep Underground Science and Engineering, EarlyView.This study presents a sustainable smart‐coating strategy for protecting underground steel infrastructures from chloride‐induced corrosion. Zinc‐aluminum layered double hydroxides (LDHs) and tannin‐loaded LDHs (LDH–TA) were incorporated into an epoxy matrix to provide both enhanced barrier properties and active, pH‐responsive inhibition.

Deep Underground Science and Engineering, EarlyView.The graphical abstract presents a steel segment–anchorage support system for open TBM tunnels under extremely intense rockburst conditions. The steel segment resists dynamic impact, while the anchorage structure restrains segment deformation and transfers loads into the rock.

The On-Line Identification and Location of Welding Interference Based on CEEMD
MetalsThe welding process itself is a non-linear, multivariable, coupled physical metallurgical process that is easily perturbed. Improper welding parameter selection and welding process conditions will interfere with the welding process and affect the final ...

Task Sequencing for Remote Laser Welding in the Automotive Industry
Proceedings of the International Conference on Automated Planning and Scheduling, 2013 This paper proposes a new model and algorithm for task sequencing in remote laser welding in the automotive industry. It is shown that task sequencing (in which order to weld the seams) is strongly related to path planning (how the welding robot should move), therefore the two problems must be solved together, in an integrated way.
