An inverse finite element method for full-field deformation reconstruction of wind turbine towers using one-sided uniaxial strain

• A novel One-Side Uniaxial-Strain Inverse Finite Element Method specifically designed for wind turbine towers is proposed. • The method introduces a novel formulation of the error functional, thereby enabling flexible adaptation to uniaxial, biaxial, or triaxial strain measurement schemes. • This method can significantly reduce the number of sensors required and the installation complexity while maintaining good reconstruction accuracy. • This method also demonstrates good robustness under sparse sensor configurations and coarse grid conditions. With the expansion of offshore wind farms into deeper and more remote seas, the operational environment for offshore wind turbine structures is becoming increasingly…
