Buckling of cylindrical shells and plates
With the use of cylindrical sections for onshore and offshore wind turbines, the question of shell buckling arises. Here we are able to measure with all methods and means commonly used today: analytical and numerical, linear and non-linear, with and without imperfections.
In the past projects, we also examined shells that were longitudinal stiffened and are very familiar with special designs of openings, conical transitions and ring stiffeners.
In the technical commitee for Eurocode 3 we initiated the removal of fixed tolerance levels, which were a remnant of thin-walled eras, in favour of relative ones. This allows heavy wall thickness shells, e.g for monopiles to be fabricated with significantly less efforts.
