Propagation of the compaction waves in a cellular block with varying cross-section

Then, an improved analytical model is proposed, incorporating the strain hardening property of the aluminum foam. Comparisons are made between the analytical models and experimental results, showing that the proposed model is able to predict the dynamic forces with sufficient accuracy. Based on the modified analytical model, typical propagations of the compaction wave are described. Correspondingly, parametrical studies are implemented based on the proposed analytical model.
