Steel support structures of offshore wind turbines (jackets and monopiles) undergo both fatigue and corrosion damage, impacting their lifetime. Due to the time‐variant uncertainties associated with environmental and mechanical loads, having reliabl

High rolling speed and high reduction are the optimal conditions for increasing the production in the cold strip rolling process. On the other hand, increasing the rolling speed and the reduction induce chatter phenomenon. This phenomenon reduces the
