In-plane crushing of a polycarbonate honeycomb
S. D. Papka,Stelios Kyriakides +1 more
TL;DR: In this paper, the in-plane compressive response and crushing of a polycarbonate honeycomb with circular close-packed cells is studied through combined experimental and analytical efforts, which is characterized by a relatively sharp rise to a load maximum followed by a drop down to an extended load plateau which is then terminated by a sharp rise in load.
