In this research, the dynamic axial and lateral compressive deformation of thin-walled circular tubes with aluminum foam glued was investigated using a special load cell for long time measurement and a high-speed video camera to measure the displacement of specimens. It was found that the maximum load and the absorbed energy up to the deformation of 60% of the total specimen deformation obtained from axial compression tests were about eight times greater than those obtained from lateral compression tests. In axial compression tests, the maximum load and the absorbed energy of tubes with aluminum foam glued were greater than the sum of individual values of empty circular tube and aluminum foam. In lateral compression tests, however, they were almost same. This is because the interaction between the thin-walled circular tube and aluminum foam in axial compression is much greater than those in lateral compression.
