The research objectives of this award are to characterize the mechanical properties of novel steel foams and determine whether this new class of materials presents opportunities for transformative improvement of the performance of civil structures. Although other kinds of metal foams serve well established purposes in the aerospace and automotive industries, the advent of manufacturing techniques for steel foams opens the door to low cost mass production of a material suitable for civil structural application. The research program consists of experiments to characterize the structure and mechanical properties of the material and simulations to establish proof-of-concept applications of steel foams to civil structures. The target applications are energy dissipating devices to improve seismic performance of building systems and selective application of steel foam to improve the strength and ductility of thin-walled steel structural members.
