Abstract: An energy absorbing device includes a honeycomb body having two or more tubes stacked transversely with one another along a longitudinal axis. The honeycomb body includes an inboard portion and an outboard portion. The inboard portion of the honeycomb body is arranged along the longitudinal axis and has an inboard portion bending stiffness. The outboard portion of the honeycomb body is arranged outboard of the longitudinal axis, is coupled to the inboard portion of the honeycomb body, and has an outboard portion bending stiffness. The outboard portion bending stiffness of the outboard portion is greater than the inboard portion bending stiffness of the inboard portion. Structural members for vehicle bodies and vehicle bodies are also described.

Abstract: An energy absorbing device includes a composite or metallic component having greater than or equal to three walls forming a component channel with a longitudinal length and a polymeric component. The polymeric component has a honeycomb structure with two or more walls defining honeycomb tubes and supported within the component channel with the honeycomb tubes stacked transversely along the longitudinal length of the component channel. Ends of the honeycomb tubes abut the composite or metal component. The composite or metal component, or the polymeric component, has a bending stiffness greater than a bending stiffness of the honeycomb structure. Rocker assemblies and vehicle bodies are also described.
