The effect of pin reinforcement upon the through-thickness compressive strength of foam-cored sandwich panels
Denis D. Cartié,Norman A. Fleck +1 more
TL;DR: In this article, it was found that the foam core stabilises the pins against elastic buckling, and the pin-reinforced core has a strength and energy absorption capacity in excess of the individual contributions from the foam and unsupported pins.
