Title: Deformation behavior and energy absorption capacity of multi-cell aluminum profiles during quasi-static axial compression
Abstract: The deformation behavior and energy absorption capacity of aluminum profiles under quasi-static axial compression were studied by quasi-static axial compression. The aluminum profiles were aged at temperature of 180 degrees from 30 min to 540 min before compression. The results indicated that the deformation mode of the aluminum extrusions was gradually changed from Diamond mode to Concertina mode and the energy absorption of the extrusions increased with increasing of aging time. The deformation mode of the aluminum sample aged for 540 min is completely concertina mode. Compared with the unaged sample, its energy absorption increased about 99%. Numerical simulation was used for accurately evaluating the load during compression deformation. The deformation behaviors were ideal and symmetrical, and the results were stable and repeatable in the simulation.
