Quasi-static and high strain rates compressive response of iron and Invar matrix syntactic foams
Dung D. Luong,Vasanth Chakravarthy Shunmugasamy,Nikhil Gupta,Dirk Lehmhus,Jörg Weise,Joachim Baumeister +5 more
TL;DR: In this paper, the authors focused on developing iron and FeNi36 Invar matrix syntactic foams and studying their properties under quasi-static and high strain rate compression, and the results showed that the yield strength decreases with increasing GMB content.

Magnesium Matrix Composite Foams—Density, Mechanical Properties, and Applications
TL;DR: An overview of hollow particle filled magnesium matrix syntactic composite foams can be found in this paper, where a comparison with similar aluminum matrix composites has been made to provide insight into the properties and weight saving potential of magnesium matrix composite composites and the comparison can guide future work and set goals that need to be achieved through materials selection and processing method development.

Quasi-static and high strain rates compressive behavior of aluminum matrix syntactic foams
TL;DR: In this paper, the compressive deformation behavior of aluminum matrix syntactic foams with varying cenosphere sizes have been studied at varying strain rates (from 10 to 3∼103 s −1 ).

Effect of hollow sphere size and size distribution on the quasi-static and high strain rate compressive properties of Al-A380–Al2O3 syntactic foams
TL;DR: In this article, the effects of hollow sphere dimensions and foam microstructure on the quasi-static and high strain rate properties of the resulting foam were examined, and it was shown that the quasistatic compressive stress-strain curves exhibit distinct deformation events corresponding to initial failure of the foam at the critical resolved shear stress and subsequent failures and densification events until the foam is deformed to full density.

Synthesis and characterization of novel ZnAl22 syntactic foam composites via casting
TL;DR: In this paper, the effect of microballoon volume fraction on the microstructure, compressive properties and strain rate sensitivity of syntactic foam composites was characterized, and the experimental results showed that the density of the foam composite containing 50-vol.% microballoons was 3.3 grams/cm 3, the plateau stress averaged 100MPa over a region of 10-60% strain, densification began at approximately 60% strain and the energy absorption was 65.5MJ/m 3.

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.
