1. IntroductionWind energy is a promising alternative for solving the challenges posed by fossil fuels and environmental contamination. To maximize the generation of energy, wind turbines are manufactured with higher towers and longer blades. However, as shown in Figure 1, the shape of thick blade roots and narrow tips causes inconsistent deformation under stress when the turbine rotates at high speed, which leads to the blade tip bending inward, increasing the risk of collision with the tower.
