recommendations! Published in 2020 at "Journal of Marine Science and Application"

DOI: 10.1007/s11804-020-00141-7

Abstract: Most wind turbine blades are assembled piece-by-piece onto the hub of a monopile-type offshore wind turbine using jack-up crane vessels. Despite the stable foundation of the lifting cranes, the mating process exhibits substantial relative responses… read more here.

DOI: 10.1080/15397734.2024.2441488

Abstract: Abstract The failure causes of a gas turbine axial compressor’s first-stage blades have been investigated in this paper. It was found that crack initiation and propagation occurred in the root region on the suction side… read more here.

DOI: 10.3390/coatings14010129

Abstract: Bushing-insert connections have emerged as efficient blade root connection designs. Bushing-insert connections with fibre-reinforced plastic (FRP) wedge-sticks enhance the strength and stability of the blade root, prevent stress concentration at the blade root, and improve… read more here.
