In this paper, the dynamic compression-shear experiments on the closed-cell aluminum foam with porosity of 72%-92% are carried out by using improved split Hopkinson pressure bar. A high speed camera is used to observe the dynamic deformation behavior of the samples on the compression-shear loading. A finite element software ABAQUS is employed to simulate the dynamic compression-shear process of closed-cell aluminum foam. The results demonstrate that there is a compression-shear band on the samples during the compression-shear loading. The most severely damaged area of the material is on the compression-shear band; Low-porosity closed-cell aluminum foam has significant strain rate effect, however high-porosity closed-cell aluminum foam can ignore the strain rate effect. The yield stress of samples decreases with increasing samples angle, whereas shear stress increase with increasing samples angle, and also the corresponding time when the samples just begin to yield decreases with increasing samples angle.

Load Distributions

The blast-resistant of an aluminum foam sandwich structure under impact has been investigated. Plastic deformation and load distributions in each of the sub-layers during and after impact were calculated by the material point method with the consideration of strain rate effect on deformation of the aluminum foam. The numerical results from the 3D material point method modeling show that the blast-resistant capability of the aluminum foam sandwich structure is excellent, and the energy absorbability of the structure would be underestimated if the strain rate effect on the aluminum foam is ignored.
