Structural Logic
Abstract
The Structural Logic program developed platform structures and frames that can adapt to varying loads and simultaneously exhibit both high stiffness and high damping. This program demonstrated the utility of negative stiffness structural elements developed under the Multifunctional Materials and Structures program, budgeted in PE 0602715E, Project MBT-01, in the ridged support frames of real world DoD platforms. As the demands on military platforms increase, so does the need for structures to mitigate the shock and vibrations applied by dynamic environments. Today's structures exhibit limited adaptability and typically achieve either extreme stiffness or damping. In military platforms, extremely stiff structures provide high strength, but readily transfer loads to passengers often resulting in serious injury. Conversely, existing damping structures can reduce the load transferred to passengers, but only at the expense of structural strength and integrity. By demonstrating the ability to combine stiffness, damping, and dynamic range in a single structure, the Structural Logic program enabled the design of military platforms with the ability to continually adapt their properties to match the demands of a dynamic environment. Technology from this program transitioned to the Navy.
