The paper presents the stability analysis of a sandwich plate of the shape of an isosceles trapezoid, subjected to unidirectional in-plane compression. The critical load value of the trapezoidal sandwich plate was obtained by a combination of the Galerkin ortgogonalisation method and the proposed method of the coordinate system transformation. An influence of plate material and geometrical properties on the critical load level was analysed. The obtained results were verified in a numerical experiment conducted with the FEM ANSYS software package.

PL

W pracy przedstawiona jest analiza stateczności sprężystej trójwarstwowej płyty o kształcie trapezu równoramiennego poddanej jednokierunkowemu ściskaniu. Wartość obciążenia krytycznego trapezowej płyty typu sandwoch uzyskano przez połączenie metody ortogonalizacji Galerkina i zaproponowanej metody transformacji układu współrzędnych. Przeanalizowano wpływ własności materiałowych i geometrycznych płyt na poziom obciążenia krytycznego. Dokonano weryfikacji uzyskanych wyników w eksperymencie numerycznym z wykorzystaniem programu MES ANSYS.
