please find a link to a story describing the results of a final project that I assigned for my graduate "Experimental Structural Dynamics" class. This is timely, on this Superbowl Sunday and the broad coverage of safety issues related to Football and head injuries.
Recent journal club posts have illustrated the interesting and unique dynamic properties of phononic crystals and acoustic metamaterials (see April and May journal club entries by M. Hussein and A. Spadoni respectively). The ability of this class of engineered materials and structures to guide and focus elastic and sound waves can be exploited in a number of new applications and exciting functionalities.
