Effect of storm loading and reconsolidation episodes on the long-term performance of an offshore monopile in a natural clay

open access: yesApplied Ocean Research
Monopiles for supporting offshore wind turbines (OWTs) in clay deposits are subjected to intermittent cyclic remoulding during severe and extreme weather events, followed by reconsolidation during normal operating conditions.

A comparative study on forming limit curves of Ti-6Al-4V alloy obtained by nakajima and elliptical hydraulic bulge tests under the effect of pulsating loading

open access: yesMaterials Research Express
Titanium alloys are increasingly employed in industrial applications due to their high specific strength, thermal stability, and excellent corrosion resistance. Among these, Ti-6Al-4V is the most widely used alloy, particularly in aerospace, gas turbine,
