2. The combination of mechanical analyses and
structural monitoring leads to better estimations to
the life of the structure and the electricity production. monitoring using
wireless sensors
Such a combination is particularly important when
icing conditions make the structural modeling more
complicated.

Corotational finite beam elements, by
non-linear dynamic model decomposing the motion into rigid body
using corotational beams and pure deformational parts, are well
adapted to model accurately the blades.
