TL;DR: In this paper, the experimental characterization and modeling of the impact behavior of a multi-functional dual core sandwich panel designed for the rehabilitation of hydroelectric turbines was studied, and a 3D numerical model was developed to simulate the impact tests and particularly the energy distribution within the sandwich constituents.

TL;DR: A threaded insert to be installed flush with the surface of an outer sheet of a sandwich panel and to be secured in the panel by a hardenable liquid adhesive is described in this paper.
Abstract: A threaded insert to be installed flush with the surface of an outer sheet of a sandwich panel and to be secured in the panel by a hardenable liquid adhesive, the insert having a flange at one end thereof with a tapered, threaded peripheral edge surface, which engages and positively grips the outer sheet along the corresponding edge of an opening in the sheet, through which opening the insert has been installed, so as to retain the insert in place within the sandwich panel, with the flange flush with the surface of the outer sheet, while the adhesive hardens.

TL;DR: In this paper, an elastic-plastic model was developed for predicting the blast response of a foam-core, curved composite sandwich panel, which was used to distinguish facesheets and core deformations.

TL;DR: In this paper, the authors investigated the impact response of composite sandwich panels with carbon-fibre/glass fibre hybrid skins with impact at velocities of 75'±'3' and 90'± '3'm's−1 using 3D digital image correlation (DIC).
Abstract: This research investigates whether the layup order of the carbon-fibre/glass-fibre skins in hybrid composite sandwich panels has an effect on impact response Composite sandwich panels with carbon-fibre/glass-fibre hybrid skins were subjected to impact at velocities of 75 ± 3 and 90 ± 3 m s−1 Measurements of the sandwich panels were made using high-speed 3D digital image correlation (DIC), and post-impact damage was assessed by sectioning the sandwich panels It was concluded that the introduction of glass-fibre layers into carbon-fibre laminate skins reduces brittle failure compared to a sandwich panel with carbon-fibre reinforced polymer skins alone Furthermore, if the impact surface is known, it would be beneficial to select an asymmetrical panel such as Hybrid-(GCFGC) utilising glass-fibre layers in compression and carbon-fibre layers in tension This hybrid sandwich panel achieves a specific deflection of 0322 mm kg−1 m2 and specific strain of 0077% kg−1 m2 under an impact velocity of 75 ± 3 m s−1 However, if the impact surface is not known, selection of a panel with a symmetric yet more dispersed hybridisation would be effective By distributing the different fibre layers more evenly within the skin, less surface and core damage is achieved The distributed hybrid investigated in this research, Hybrid-(GCGFGCG), achieved a specific deflection of 0394 mm kg−1 m2 and specific strain of 0085% kg−1 m2 under an impact velocity of 75 ± 3 m s−1 Blast loading was performed on a large scale version of Hybrid-(GCFGC) and it exhibited a maximum deflection of 75 mm following a similar deflection profile to those observed for the impact experiments
