Abstract
Dynamical deformation and collapse process and stress wave mechanism of an aluminum honeycomb with a defective cell subjected to the in-plane impact of a rigid impactor were investigated experimentally. Deformation process was visualized using a high-speed video camera and a CCD camera and wave propagation mechanisms were investigated using a force gauge at the fixed end and strain-gauges glued on the cell walls. Also, numerical simulation was made using a shock code, AUTODYN-2D. The defect introduced in cells greatly affects wave propagation mechanisms and cell deformation process. The present results were compared with our previous results.
