Structural analysis and design optimization of wind turbine blades


DTU Wind Energy, Technical University of Denmark
Finite Element Model

The blade is now modelled using N=20 beam finite elements (1 element per “section”).

The 4-noded beam finite elements are from FRANS, which comes with DTU Wind Energy’s cross section analysis software BECAS (

A description of the beam finite element model is contained in the description of mini-project 2, which can be downloaded from DTU Inside.
