The Dynamic Properties of Sandwich Structures based on Metal-Ceramic Foams
The transportation sector is constantly looking for high-performance materials in order to reduce structural weight as well as to enhance crashworthiness issues. One of the answers to these needs is the incorporation of a foam technology. Currently, applications of non-ferrous foams in the automotive field include floor panels, bumpers and door side bars. In the case of aircrafts and railroads, their applications concentrate on collision posts and crash cages, crush buffer zones and side impact barriers on rail passenger cars. Indeed, their use is also emerging in the military systems as lightweight armor for army trucks and personnel carriers, mine blast containment and water-tight doors on ships. Although their use is continuously growing in the transportation sector, there are still a number of properties that need to be largely improved mainly under impact (dynamic) conditions. Besides, federal agencies such as the Air Force are interested in high-performance materials under extreme conditions. Hence, this proposal perfectly fits into the current need of the transportation sector by investigating the mechanical performance of novel ceramic-metal materials under low and high velocity impact tests as well as under high-strain rates using a Hopkinson Pressure Bar (a specialized equipment for measuring stress-strain behavior under extreme conditions).
