Experimental Testing of Single APM Spheres

Abstract

Abstract. Advanced pore morphology (APM) foam, consisting of sphere-like metallic foam elements, proves to have advantageous mechanical properties and unique application adjustability. Since the APM foam manufacturing procedure has been developed recently, the mechanical characterization of these materials is still very limited. Therefore, the purpose of this research was to determine the behaviour of APM spheres and its composites when subjected to quasi-static and dynamic compressive loading. The results of the performed research have shown valuable mechanical properties of the composite APM foam structures, offering new possibilities for their use in general engineering applications.

New Aluminum Syntactic Foam: Synthesis and Mechanical Characterization

“…The research groups of Vesenjak, Krstulovic-Opara, and Duarte have extensively studied aluminum expanded nodules foamed with TiH2 (APM). Compressive testing on APM made of AlSi7 and AlSi10 matrices ranging from 5 to 10 mm in size demonstrated great potential for their use in general engineering applications [ 33 , 34 , 35 ]. Diverse hybrid foam approaches were tested based on the APM potential, and its incorporation as a filler of polymer SF, aluminum tubes and to obtain open cell foam structures was found to be beneficial [ 36 , 37 , 38 ].…”

The effect of production parameters on the foaming behavior of spherical-shaped aluminum foam

“…They can be used as team members in front of vehicles by filling inside of steel pipes [13][14][15] . Recently, the researchers has focused on the mechanical properties of the single or hybrid APM foams 16,17 . However, the researches on the effect of process parameters in production of these materials are still very limited.…”
