In fact, steel, on average, represents 80 percent of all the materials used to construct a wind turbine. The main components of the machine are the tower, the nacelle and the rotor. While the blades are generally made of other materials, such as carbon fiber or alloys, steel holds the turning blades in place, utilizing a cast iron or forged
The adapter is an essential part of the wind turbine hybrid tower since the steel and the prestressed concrete segments are connected by the adapter. Due to the large designed prestress, the adapter is prone to fail under compression. Consequently, the ultimate capacity of the adapter under compression is critical to the safe operation of the
