Abstract
An apparatus is provided that includes a structure. This structure includes a first skin, a second skin and a cellular core connected to the first skin and the second skin. The cellular core includes a cantilevered damper and an internal cavity between the first skin and the second skin. The cantilevered damper projects into the internal cavity. The cantilevered damper includes a plurality of damper masses and a plurality of damper arms interconnecting the plurality of damper masses together.
