Paper Abstract

Deformation processes of aluminum honeycombs with hexagonal cells subjected to the in-plane impact of a rigid impactor are investigated experimentally and numerically in relation to the dynamical behavior of cellular materials and complex materials under high-speed loadings. Strain waves are measured using strain gauges glued on the cell walls and reaction forces are measured using a load cell at the contact surface between the honeycomb and a fixed wall. A high-speed camera is used to visualize the deformation process. Numerical simulations are partly made for the same configuration as the experiment. Very distinctive deformation mechanisms of individual cells and propagation mechanisms of strain waves in the honeycomb are found out. Also, characteristic two-dimensional behavior is revealed in spite of one-dimensional and uni-directional impact loading.
