Description
  • Příspěvek se zabývá modelováním skořepin. Jednou z možností jak vytvořit numerický model skořepiny je aproximovat její zakřivenou plochu několika rovinnými oblastmi. Tento postup je ukázán na numerických modelech válcové a kuželové skořepiny. Výsledky získané z těchto modelů jsou porovnány s řešením těchto konstrukcí membránovou teorií. Při dostatečně jemném rozdělení skořepiny na rovinné podoblasti jsou výsledky získané výpočtem metodou konečných prvků téměř stejné jako z membránové teorie. Jedinou výjimku tvoří místa podepření konstrukce, kde dochází k poruchám membránové napjatosti. (cs)
  • This contribution deals with the modeling of shells. One of the possible methods how to numerically model a shell is to approximate its curved surface by several plane areas. This method is demonstrated on the numerical models of a cylindrical and conic shell. The results obtained from these models are compared with the solution of these structures by the membrane theory. If the shell is divided into a sufficient number of plane sub-areas, the results obtained by the Finite Element Method are nearly the same as those obtained by the membrane theory. The only exceptions from these results are those places of the shell support where the failures of the membrane state of stress occur.
