—The paper deal with numerical studies of dynamic axial loading of thin-walled metallic titanium alloy extrusion double cell polyurethane foam-filled square. Nonlinear dynamic simulations were performed on empty as well on foam-filled modeling. The dynamics non-linear finite element code ABAQUS standard and explicit were used to simulate the buckling and crushing of columns. The influence of filler material on energy absorption and behavior of double cell thin-walled square metallic titanium alloy extrusion were examined. Three main collapse modes were identified for the crushed model, such as compound diamond asymmetric, concertina axisymmetric and mixed mode fold formations. Three different arrangement of double-cell inner column were examined and investigated. Filling the polyurethane foams into tubular double cell played important factor positively influencing the energy absorption capability. Results showed that the tubular energy absorption capability was affected significantly by varying of velocity impact and wall-thickness as well as arrangement inner tube cross-section
