Hi
from a German Lloyd report about the certification of blades, I read that the failure criteria used up to know by aerospace community are not so reliable as one could think. The Puck failure criteria is mentioned as the most suitable for wind turbine.
What is the thought of NREL about this topic ?

Certification and failure criteria
Corrado,
We don't have a lot of expertise in materials here at NREL. I've never even heard of the Puck failure criteria. However, Sandia National Labs, our sister lab, has very extensive experience in that field. Hopefully, one of them will see this post and respond. I believe they are aware of this forum.
