Vibrations, stability and compression of elements of packages made from corrugated board

The paper considers vibrations, stability and compression of a package element made from corrugated board. The analysis is based on a model of a structure consisting from twodimensional beams taking into account the orthotropic properties of the corrugated board. The problem of initial stability was solved and the first eigenmodes of stability were obtained. Performed experimental study allowed to determine the dependence of the vertical compression force on the geometrical parameters of the multilayered board before the development of plastic deformations in the board. The results of investigation are used for the design of package elementsKauno technologijos universitetasVytauto Didžiojo universiteta
