Original abstract

The questions of the buckling of thin walls structures (stiffened panels) are solved for a long time by many well-known scientists. A lot of theories and design processes have been found to predict a buckling and stability of stiffened panels. Nevertheless even today we are not able to ensure absolutely precise buckling prediction of the stiffened panel. It means that it is still very important design stage a testing and experimental verification of the theoretically calculated data. The experimental results are very valuable not only to verify the theoretical calculations but also to find and specify coefficients and last but not least this data are useful to creation a graphs and relations. Very similar reason to experimental verification of compression of stiffened panel is also in our case. The experimental data will be used for debugging for the optimization software OPTPAN [1].

Czech abstract

Problematika únosností a stabilit tenkostěnných konstrukcí je předmětem intenzivního zkoumání již poměrně dlouho a během této doby se jí věnovala spousta významných autorů. Za tuto dobu vznikla celá řada teorií a postupů jak vhodně navrhnout danou tenkostěnnou konstrukci (Vyztužený panel), nicméně všechny tyto postupy jsou pouze přibližné a stále se při návrhu neobejdeme bez experimentálního ověření teoreticky dosažených výsledků. Proto bylo navrženo vlastní experimentální zařízení, které slouží k ověření výsledků dosažených pomocí optimalizačního programu OPTAN [1].
