【 摘 要 】

stoplastic bending of a sandwich beam with a rigid compressible filler on an elastic base has been studied. To describe kinematics of asymmetrical across thickness pack in the bearing layers the Bernoulli hypotheses have been accepted. Displacements in the filler vary linearly over thickness. The distributed superficial loading simulates the hydrostatic effect of the ambient liquid. The reaction of the base is described by Winkler's model. A system of equilibrium equations for displacements has been obtained and solved. The numerical results for a sandwich metal-polymer-metal beam are cited.
