摘要

The boundary effects induce in the vicinity of a junction between two different core materials in a sandwich panel are analyzed using a third-order shear model of cylindrical bending. Closed-form analytical estimates for the local bending stresses are derived for the cases of both similar and dissimilar faces. Two criteria for the estimation of the relative contribution of the local face stresses to the total stress state are proposed, and an example of their practical application is presented.
