pressure failure model is suitable for aluminum foams. Due to the similarity of the stress-strain diagram, the specimens of this study are predicted with aluminum foam. This material has relatively similar behaviours to aluminum foam in behaviours with the blast wave, but it is difficult to define some parameters in this method. Explosion tests have been used in this study.

Figure 6: Various granulation of pumices.

In this study, two sizes of almond mineral pumice (maximum dimensions of 3 cm) and pea mineral pumice (maximum dimensions of 1 cm) are used and two types of pumice with grey colour are used. Fig. 7 shows an almond granular pumice. Fig. 8 shows how to make test specimens.
