Original abstract

Shell constructions, which are widely used in process industry, can be rendered unstable on certain terms. When performing stability test, in some cases calculations according to standards can be used, however complicated constructions are mainly tested by Final Element Method (FEM) buckling analysis. Despite the fact, that above mentioned methods are using perfect geometry, loss of stability in a real construction is affected by imperfections. Purpose of this work is to compare different ways of implementing imperfections into stability test procedure in FEM software ANSYS.

Czech abstract

Skořepinové konstrukce, hojně používané v procesním průmyslu, mohou být za určitých podmínek nestabilní. V některých případech lze ověřovat stabilitu konstrukcí výpočty podle norem, složitější případy jsou testovány analýzou boulení pomocí metody konečných prvků (MKP). Přestože výše zmíněné metody předpokládají dokonalou geometrii, ztráta stability skutečných konstrukcí je ovlivněna nedokonalostmi. Účelem této práce je porovnání různých způsobů zahrnutí nedokonalostí do procesu ověřování stability v MKP software ANSYS.
