The subject of the study is a sandwich plate-strip subjected to a four-point load. An analytical model of the strip was developed, taking into account the classical zig-zag theory, namely the broken line hypothesis. Three parts of the plate-strip are distinguished: two of them are the edge parts, where bending and the shear effect is considered, the third one is the middle part subjected to pure bending. The total maximum deflection of the plate-strip and the maximum deflection of the selected middle part of the plate-strip are calculated. The FEM-numerical study is carried out similarly to the analytical approach. The experimental study was carried out on the test stand in the Institute of Rail Vehicles TABOR. The analytical, numerical and experimental results are compared each with other. The sandwich panels can be used as parts of the floor or rail vehicle paneling.
