Bending study of submarine power cables based on a repeated unit cell model

Predicting the bending behaviours of a submarine power cable (SPC) is always a tough task due to its complex geometry and inner layer contact, not to mention the stick–slip mechanism. A full-scale finite element model is cumbersome during the early design stage and a more efficient model for practical use is required. Therefore, in this paper...

Mechanical responses of submarine power cables subject to axisymmetric loadings

Submarine power cables are considered lifelines in wind farm engineering, playing a key role in transporting electric current produced by wind turbines or wave converter. Cables inevitably confront combined loadings in deep-sea areas, affecting the integrity and safety during their installation and application. In this paper, the mechanical...

Investigation into Atomic Diffusion at the Interface During Extrusion Welding of Magnesium and Magnesium Alloys

This research was aimed to reveal atomic diffusion across the bonding interface through the extrusion-welding experiments of dissimilar materials, namely pure magnesium and Mg–Al–Zn–RE alloy. A special tooling setup used to simulate weld seam formation during extrusion through a porthole die was designed for this model study. To deform the...
