Abstract

In all branches of industry, especially in power-engineering, thin wall steel structures are extensively used. Land vertical cylindrical steel tanks are very popular ex-amples of such structures. Manufacture and assembling of these structures are usually accompanied by the deviations from a perfect cylindrical form. Therefore, exact evaluation of real local imperfections and common deviations from the analytical model of the tank is very important for such potentially dangerous structures.The main objectives of the presented investiga-tions are: to describe some results of experiments of thin plates with a defect; to identify stress and strain state by using the finite element method; to make the comparison between experimental results and FEM results. The final remarks and conclusions have been presented.
