Stateczność prostokątnych płyt przekładkowych o zmiennej sztywności wypełniacza

Władysław Walczak, Maria Kotełko

In the paper an influence of variable rigidity of the core on general stability of rectangular sandwich plates was considered. In considerations the special numerical method was utilised. Application of the method allowed for determination of coefficients of the plate critical loading at the assumption that the rigidity of a plate core is discretely varying. Exemplary results of numerical computations, carried out for some chosen cases of a disk loading, were also presented.
