Cellular Aluminum for Use in Energy Dissipation Systems
Abstract
This study was initiated under the sponsorship of the NASA Langley Research Center for the purpose of developing cellular aluminum structures for use in energy dissipation systems. These cellular structures are attractive for such applications because of their inherent isotropic properties and their great capacity for energy absorption through collapse of the cells in the structure. Since the specific applications are intended for space exploration, the problem of energy absorption capacity per unit of weight is also of the greatest importance. These materials will be required to absorb energy at loading rates which will not exceed 100 feet per second. Prior work at NASA Langley Research Center has shown that the results obtained with slow speed compression tests correlate with the results obtained at the anticipated rates of loading. In order to expedite the study, testing for material evaluation was confined to the slower speeds obtainable with conventional testing machines.
