Fatigue Behaviour of Functionally Graded Steels Produced by Additive Manufacturing

Wire arc additive manufacturing (WAAM) can create large parts, due to its high deposition rate. WAAM can be used to create functionally graded materials (FGMs) such as a strong core of high strength low alloy (HSLA) steel and corrosion-resistant cladding of austenitic stainless (AUS) steel. However, HSLA and AUS steel are dissimilar metals with...

Assessing the post-hooking lifetime of hydrogen pipelines damaged by anchors

The increasing focus on reducing greenhouse gas emissions has led to the attractiveness of offshore hydrogen pipelines in achieving sustainable energy goals. Hydrogen, as a transport medium for energy, offers a viable alternative for transmitting large amounts of energy from offshore facilities to the shore. By storing hydrogen and subsequently...

Development of a numerical evaluation strategy for predicting crack branching and crack turning in the latest generation aluminium alloys

Artificially aged aluminium-lithium alloys have recently seen renewed interest in them in the aviation industry. They have a decreased density, while keeping or improving the fatigue properties compared to other aluminium alloys. Research shows that these aluminium-lithium and other advanced aluminium alloys exhibit crack turning and crack....

Fatigue Crack Growth in Solid Round Metallic Bars with a Shoulder Fillet

Solid round bars with a shoulder fillet are frequently used in engineering structures because it facilitates a smooth transition in thickness. However, the presence of shoulder fillets is currently neglected in the prediction of fatigue crack growth in engineering practice. Since stress concentrating locations like a shoulder fillet can have a...
