Abstract
The dynamic stress-strain relationships of the alumina with alternately dense and porous layers were characterized by a split Hopkinson bar. The yield stress increased with increasing the impact velocity at a fixed porosity, and at a given strain rate, the plateau region prolonged and the yield stress decreased with increasing the porosity. The layered alumina exhibited similar dynamic fracture behavior with the aluminum alloy foam.
