Abstract

Abstract

Deformation behavior of closed-cell metallic foam under uniaxial dynamic compression was investigated using the finite element method of ABAQUS/Explicit code. The random 3D Voronoi technique was employed to construct foam specimens. Three deformation modes, namely the quasi-static homogeneous mode, the transitional mode and the shock mode, had been observed in the foam specimens with increasing of impact velocity. A deformation mode map with coordinates of relative density and impact velocity was presented for the foam considered. Two parameters, namely the stress uniformity index and the deformation localization index, were introduced to identify two critical impact velocities of mode transitions. The numerical results of critical impact velocities were compared with the predictions using the theoretical formulas from the literature. Based on the numerical and theoretical results of critical impact velocities, a scheme is suggested to determine the locking strain. It is found that the locking strain obtained from this scheme is between the densification strain and the complete densification strain.
