Compression properties of syntactic foams: effect of cenosphere radius ratio and specimen aspect ratio
TL;DR: In this paper, the effect of change in the internal radius of cenospheres was investigated for flatwise (specimen aspect ratio of 0.5) compressive properties of syntactic foams.

Experimental study of energy absorption in a close-celled aluminum foam under dynamic loading
TL;DR: In this paper, the authors determined the minimum height of aluminum foam specimens for compression test at a quasi-static strain rate by comparing the specific yield stress (i.e., yield stress per (relative density),sup 3/2}) of the foam with other data previously reported.

High strain rate compression of closed-cell aluminium foams
TL;DR: In this article, the compressive deformation behavior of open-and closed-cell aluminum foams was assessed under static and dynamic loading conditions, and high strain rate experiments were conducted in a laboratory using a split Hopkinson pressure bar system at strain rates ranging from 400 to 2500 s−1.

Plasticity and Damage in Aluminum Syntactic Foams Deformed under Dynamic and Quasi-Static Conditions
TL;DR: In this paper, synthetic foams were fabricated by liquid metal infiltration of commercially pure and 7075 aluminum into preforms of hollow ceramic microspheres, which exhibited peak strength during quasi-static compression ranging from −100 to −230 MPa, while dynamic compression loading showed a 10-30% increase in peak strength magnitude, with strain rate sensitivities similar to those of aluminum-matrix composite materials.
