This is an open access article under the CC BY-NC-ND license (https://creativecommons.org/licenses/by-nc-nd/4.0) Peer-review under responsibility of DMDP 2023 Organizers Abstract During operational conditions, the cylindrical shell wind turbine tower is susceptible to bending moments caused by lateral wind gushing towards the wind turbine tower, which often leads to fatigue failure on the tower structure. Hence, the assessment of the flexural strength of wind turbine towers is an important study in order to develop a robust wind turbine system. In the present study, the flexural strength of steel cylindrical shell structure with a diameter-to-thickness ( D / t ) ratio ranging from 75 D / t 150 is analyzed using finite element method with ABAQUS software, and the numerical result is later compared with the data taken from experiment. The result reported that current numerical simulation has been able to closely predict the actual flexural strength of the cylindrical shell structure. In general, the prediction of the ultimate load is sensitive to the mesh size, even though, at a certain point, the effect of mesh size would no longer be significant. Mesh size also affects the final deformation shape of the cylindrical shell, whereas a larger mesh size tends to generate more realistic and visible deformation. © 2024 The Authors.
