A fluid–structure analysis approach and its application in the uncertainty-based multidisciplinary design and optimization for blades

Advances in Mechanical Engineering, 2018
In practical engineering, the choice of blade shape is crucial in the design process of turbine. It is because not only the structural stability but also the aerodynamic performance of turbine depends on the shape of blades.
