000015345 520__ $$2eng$$aRecent studies by the authors for the behaviour of the graded cellular foam are summarized in this presentation. Finite element (FE) simulations employing a honeycomb structure were presented first to investigate the in-plane impact modes. Subsequently, a simple onedimensional analytical work was proposed based on the rigid-perfect plastic-locking (R-PP-L) material model. Gradient in yielding strength was introduced to a one-dimensional cellular rod. A more-realistic case, in which a gradient in the cellular density was later introduced. Two compaction zones, known as double shock mode, were identified. An impact experiment was designed to test specimens (ALPORAS closedfoam aluminium foam) with graded cross-sections along the impact direction. Comparisons are made between the experimental and theoretical results, which shows a fairly good agreement.
