Abstract: | The elastoplastic bending of a sandwich bar with a stiff compressible core on an elastic foundation is studied. The kinematics
of the bar, which is asymmetric across the thickness, is described adopting Bernoulli’s hypotheses for the face layers. The
displacements of the core are assumed to vary linearly across the thickness. The foundation is described by the Winkler model.
A system of equilibrium equations for displacements is derived and solved. Numerical results for a metal-polymer sandwich
bar are presented
