Spinning finite element analysis of longitudinally stiffened horizontal axis wind turbine blade for fatigue life enhancement - ScienceDirect
In this study, a proof-of-concept is presented for extending the fatigue life of modern multi-megawatt wind turbine blades. For this purpose, spinning finite element model of the blade is investigated which has longitudinal stiffener (i.e. a tendon along its length) made of shape memory alloy. The material behaviour of the tendon is characterized by Liang and Rogers constitutive model in combination with thermodynamic principles...
