TL;DR: In this paper, a finite element model was developed describing the interlaminar and intralaminar damage of composite sandwich panels; this model was validated by in-plane compression experiments.

TL;DR: In this paper, a multi-level, multi-functional, optimisation methodology is suggested for the design of a composite high speed train car body, which consists of a layer of inner lining (glass fibre/vinyl ester), a layerof fibrous insulation, and a load carrying sandwich panel (carbon fibre/epoxy face sheets on a PMI core).
Abstract: A multi-level, multi-functional, optimisation methodology is suggested for the design of a composite high speed train car body. The structure consists of a layer of inner lining (glass fibre/vinyl ester), a layer of fibrous insulation, and a load carrying sandwich panel (carbon fibre/epoxy face sheets on a PMI core). Besides the most commonly used design constraints, such as mechanical strength, stiffness and geometry, also acoustic and thermal insulation as well as fire safety is included in the optimisation. The results suggest that well over 40 % mass reduction can be achieved with these types of structures.

TL;DR: In this article, a combined experimental, numerical and analytical approach is employed to investigate the nonlinear effect of incident sound pressure level (SPL) on the sound absorption performance of a novel ultralight sandwich panel with perforated honeycomb-corrugation hybrid (PHCH) core.

TL;DR: In this paper, a procedure for calculating homogenized orthotropic plate stiffnesses of the sandwich was developed and applied to a number of different profiles and the effect on uniaxial and shear buckling was investigated.
