Buckling and vibrations of metal sandwich beams with trapezoidal corrugated cores – the lengthwise corrugated main core
AbstractThe paper is devoted to the stability of an orthotropic multi-layered beam. This beam is an untypical sandwich structure the faces of which consist of three layers. The original mathematical model of the beam is formulated taking into account different properties of each layer. From the Hamilton's principle the system of equations of motion is derived which is the base for the analysis of buckling and vibration problems. As a result of the analysis the buckling load and natural frequencies of exemplary plates have been obtained. The results are compared with these given by the numerical solution realised with the use of the finite element method in the ANSYS and ABAQUS systems.
HighlightsAn original mathematical model of a multi-layered beam is proposed.Buckling and vibration of presented structures is analysed.The stiffness of the beam is very high in relation to its mass.Mechanical properties of the beam can be easily modified by changing corrugations.
