“…Compared with the traditional metal materials, fiber‐reinforced polymer composites have special advantages on strength, stiffness, and fatigue durability. Therefore, they are widely applied in aeronautics and astronautics engineering, 1,2 vehicle, 3,4 and wind turbine blade structure 5,6 . In these engineering structures, the composite components are subjected to the random loadings from acoustic and vibrational environment.…”

In this paper, the fatigue properties of the plain weave composite subjected to broadband random loading are investigated. A prediction method is proposed to calculate the failure probability of the composite under random loading by combining the probability density function of the residual strength and the probability density function of the stress peaks. The stress randomness and the strength dispersity are both taken into account in the analysis of the residual strength and the failure probability curves. The fatigue life data of the plain weave composite under broadband random responses are obtained from the random vibration tests. The predicted results are in good agreement with the experiments.

“…O projeto de uma pá de turbina eólica leva em conta os aspectos aerodinâmico e estrutural. A sua forma externa é dominada pelas questões aerodinâmicas, já no seu interior, o fator dominante é o estrutural (Mølholt Jensen;. A Figura 3 ilustra um esboço de uma típica pá, nela a geometria externa é chamada de carenagem e dentro há duas estruturas que ligam a parte superior com a inferior, chamadas shear webs, sua principal função é resistir aos carregamentos cisalhantes quando a pá está sob flexão .…”
