Abstract

Sandwich structures are notoriously sensitive to failure by the application of concentrated loads, at points or lines of support, and due to localized bending effects induced in the vicinity of points of geometric and material discontinuities. The reason for this is that localized shearing and bending effects induce severe through-thickness shear and normal stresses. These through-thickness stress components can be of significant magnitude, and may, in many cases, exceed the allowable stresses in the core material (as well as in) especially close to the interfaces between the core and the face sheets.
