Onshore wind energy is a mature market with electricity production costs sharply decreasing . One of the main approaches to further reduce these costs is to improve our knowledge of the lifetime of major components of wind turbines, such as blades. This project will provide a novel protocol to estimate accurately the lifetime and residual lifetime of the wind blades to optimize their maintenance and management. 


The ONSHORE project aims to propose a methodology to estimate the accumulated damage in bonded composite structures taking into account the effects of the implentation procedures on the mechanical strenght of the assemblies. The objective is to characterize the behavior and damage of bonded composite materials at different levels (coupons and representative structure).
