Hydrogen is a carbon-free fuel that can facilitate the progress of achieving net-zero
emission. The use of the existing natural gas pipelines for hydrogen transport is an essential …

The accurate determination of residual stresses has a crucial role in understanding the
complex interactions between microstructure, mechanical state, mode (s) of failure, and …

The welding of steel generates substantial welding residual stress (WRS), which exerts a
significant impact on the fatigue life of steel bridges. In this study, a physical model for …

We investigate the implications of conducting hydrogen-assisted fatigue crack growth
experiments in a hydrogen gas environment (in-situ hydrogen charging) or in air (following …

Fracture resistance of pipeline welds from a range of strength grades and welding
techniques was measured in air and 21 MPa hydrogen gas, including electric resistance …

We combine welding process modelling with deformation–diffusion–fracture (embrittlement)
simulations to predict failures in hydrogen transport pipelines. The focus is on the structural …

Hydrogen is an environmentally friendly fuel that can facilitate the upcoming energy
transition. The development of an extensive infrastructure for hydrogen transport and …

The new extreme faces strain gauges (XFS) technique, when compared to the direct current
potential drop (DCPD) and back face strain gauge (BFS) methods, has shown superior …

High strength steel welded joints are usually fabricated by heterogeneous weld metal for
reducing the negative impacts of microstructural characteristics and defects on mechanical …

To overcome the limitations associated with the conventional fabrication (eg, casting,
forging, assembly) of large-sized complex structures, in this study, we assess large format …
