Climate change is rapidly forcing the world to create renewable energy that is capable of sustaining future energy requirements globally The generation of renewable energy at a comparatively lower cost is a major challenge for this industry Unforeseen weather conditions and environments such as offshore conditions or involving acid rain have a significant effect on the degradation of

2017-4-1The region of interest in the erosion study is the tip of the blade which is most frequently subjected to the highest impact velocities Using impact pressure predictions available for all the drops in a given rain scenario (see Fig 1 see also Amirzadeh et al (2017)) the rain-induced stresses in the blade shell can be calculated using a detailed transient stress analysis
