High‐Order Theory for Sandwich‐Beam Behavior with Transversely Flexible Core
TL;DR: In this paper, a general high-order theory based on variational principles is presented for the bending behavior of a sandwich beam with a core that is vertically flexible, which embodies a rigorous and systematic approach to the analysis of such structures, which have highorder effects caused by the nonlinearity of the longitudinal and the transverse deformations of the core through the height.

Failure mode maps for honeycomb sandwich panels
A. Petras,Michael P.F. Sutcliffe +1 more
TL;DR: In this article, failure modes for sandwich beams of GFRP laminate skins and Nomex honeycomb core are investigated and a failure mode map for loading under 3-point bending is constructed, showing the dependence of failure mode and load on the ratio of skin thickness to span length and honeycomb relative density.
Journal ArticleDOI
Failure mode maps for foam core sandwich beams
TL;DR: In this paper, the authors developed a failure mode map, with axes of core relative density and the ratio of face thickness to span length, which, for a given loading configuration and set of face and solid core materials, shows the dominant failure mode for every possible beam design.
