Abstract |
The bending collapse behavior of extruded aluminum and hybrid beams was studied theoretically and experimentally. Very good agreement was found between the theoretical results for extruded square section tubes with some partitions. For seam bending energy absorption, the hybrid beams achieved significant reduction of weight compared with traditional reinforced thin-walled steel beams. The strain rate dependence of different heat treated extruded aluminum was explained by the high speed tensile tests. Static and dynamic bending tests were carried out to investigate the influence of different materials, heat treatments and sections on bending energy absorption. |
