Optimal design of honeycomb material used to mitigate head impact

The aim of this study is to identify the best possible design of honeycomb material in order to lessen impact forces. To do this, it is necessary to choose parameters that minimize the thickness of the honeycomb structure while still providing adequate protection for impact resistance in order to prevent injury. The study used explicit dynamic finite element analysis to represent an unprotected drop of a rigid impactor onto a simulated floor composed of vinyl composition tile and concrete. This was compared to the use of honeycomb material to reduce accelerations, and the affect of parameters such as honeycomb material modulus, wall thickness, cell geometry, and structure depth was compared to the unprotected drop. Selecting the minimum honeycomb depth possible is preferable, because smaller dimensions improve aesthetic design, which makes the device more likely to be used.
