Quasi-static impact of indented foldcores

Abstract:

A modified planar foldcore geometry was developed by introducing sub-folds into a standard foldcore pattern. It was demonstrated using numerical simulation that the new geometry, deemed the indented foldcore, successfully triggered a high-order travelling hinge line failure mode. This was found to have a much higher and more uniform energy absorption than the plate buckling failure mode seen in a standard foldcore structure. A numerical analysis also established optimum standard and inden...
