An overview is given of the activities of the project "Improved design for large wind turbine blades (Phase 3)", partially supported by the Danish Energy Agency under the Ministry of Climate and Energy through the EFP-grant no. 33031-0078. The project was focussed at the development of new design methods for wind turbine blades, so that uncertainties associated with damage and defects can be reduced.
The following topics with respect to failure modes were covered: Buckling-driven delamination of loadcarrying laminates, cracking along interfaces in material joints, implementation of cohesive laws in finite element programmes and hierarchical finite element models. Methods and major research results of the project are summarised.
Some future goals for future research activities are briefly discussed.
