Collapse mechanisms of sandwich beams with composite faces and a foam core, loaded in three-point bending. Part II: experimental investigation and numerical modelling
Craig A. Steeves,Norman A. Fleck +1 more
TL;DR: In this paper, the authors focus on the competing collapse mechanisms for simply supported sandwich beams with composite faces and a PVC foam core subjected to three-point bending, and a failure mechanism map is constructed to reveal the dependence of the dominant collapse mechanism upon the geometry of the beam.

Aluminium foam sandwiches collapse modes under static and dynamic three-point bending
Vincenzo Crupi,Roberto Montanini +1 more
TL;DR: In this paper, the structural response (collapse modes, energy dissipation, strain rate sensitivity) of two different typologies of aluminium foam sandwich (AFS) panels, consisting of a closed-cell aluminium foam core with either two integral (Schunk) or two glued (Alulight) faces, was investigated.

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.
