Abstract

Abstract

To examine the rate-dependent properties of aluminum foams, three-dimensional random spherical cell models were constructed to simulate the microstructures of aluminum foams, and the dynamic deformations of aluminum foams at the strain rates of 10-10 000 s^-1 were calculated by using the ANSYS/LS-DYNA commercial code.Obtained results show that at moderate and low strain rates, the rate-dependent properties of aluminum foams originate mainly from the strain-rate sensitivities of their matrix materials.At high strain rates, the rate-dependent properties of aluminum foams are dominated by the combining action of the strain rate sensitivity of cell materials and the microstructure inertia of cells, and the microstructure inertia effects are more remarkable for aluminum foams with low relative density than for those with high relative density.
