Experimental and Simulation Study of Honeycomb Core under Dynamic Loading

The objective of this project is to get the energy absorption aluminium honeycomb core through experimental work and simulation analysis. force-displacement behavior absorb are studied for two different cell sizes core, which 0.0127 m 0.01905 m, respectively. out-of-plane dynamic compression tests conducted specimens by using INSTRON CEAST 9340 drop tower machine with an impact mass 25 kg at 800 mm height generate velocity 3.96 m/s. linear elastic regime, flat plateau force regime densification observed in crushing core. In finite element simulation, model structures size created ABAQUS 6.12 explicit environment. Several parameters such as mesh sizes, time intervals plasticity models Isotropic hardening Johnson-Cook investigated validated results. 1 500-time interval optimum modelling where buckling mode specimen similar work.
