  ABSTRACT: A new method has been established to predict the compressive strength of cenosphere–aluminum syntactic foams, showing the relation between the relative wall thickness of the cenopshere and the compressive strength of such foams. Quasi-static compression tests indicated that annealed cenosphere–aluminum syntactic foams can deform plastically at a relatively higher stress (∼45–75 MPa) and their energy-absorbing capacity can reach ∼20–35 MJ m−3. The deformation mechanisms of syntactic foams have also been discussed.

  ABSTRACT: The high strain rate compression behavior of cenosphere–pure aluminum syntactic foams has been studied by comparing it with the results from the quasi-static loading condition. The foams exhibited distinct strain rate sensitivity and the peak strengths increased from ∼45–75 to ∼65–120 MPa; the energy absorption capacity also increased by ∼50–70%. A three-parameter data-fitting equation has been developed to predict the rate-dependent compressive stress at relatively low strains for the syntactic foams.
