Abstract
Influence of different edge boundary conditions for the core and for the faces on deflections of the asymmetric sandwich strip and beam, with ends enabling carrying the bending moment are investigated in the paper. Two kinds of asymmetry of the clamped-clamped (C-C) sandwich structure are taken into account namely, asymmetry of faces and asymmetry of fastening of the faces to edge inserts. Numerical results which are presented to demonstrate the influence of the core conditions have been obtained according to a new analytical 2D model and by FEM. In order to make the analysis more valuable some experimental results have been compared. Influence of different edge conditions for the core, edge in-plane displacements of faces as well as asymmetry of faces and their fastening to inserts on the strip and beam deflection is examined. The usefulness of the new 2D model for validation of the FEM models is shown. All considerations and results refer to the sandwich structures composed of isotropic layers.
