This article investigates the quasi-static compressive behavior and the drop weight impact tests during the crashing of energy-absorbing structures such as aluminum foam-filled tubes. The closed-cell Al and A356 Alloy foams were cast and, after cutting, inserted into the Al thin wall tube as axial fillers of single-, double- and quad-layer structures. Then, the specific energy absorption (SEA), complementary energy (CE), normalized energy (NE), and specific normalized energy (SNE) are calculated based on static and dynamic test results under uniaxial loading. In this new method, values of NE and SNE are always between 0 and 1. Results show that the SEA-strain curves obtained from crashing the foam-filled tubes were linear and overlapping under static and dynamic loading. However, NE curves for dynamic tests were cyclic and in the static tests were asymptotic non-linear, and utterly separable. Results indicated that the SNE for Al, A356 single layer, Al-A356 double-, and Al-A356-Al-A356 quad-layer foam-filled tubes during dynamic tests were 0.25, 0.29, 0.31, and 0.31, while for the static tests, 0.14,0.15, 0.17, and 0.14 were recorded. It was found that CE and NE energies were better than the SEA energy for recognizing plastic deformation and crushing behavior.

本文研究了泡沫铝填充管等吸能结构在碰撞过程中的准静态压缩行为和落锤冲击试验。将闭孔铝和 A356 合金泡沫浇铸，切割后插入铝薄壁管作为单层、双层和四层结构的轴向填料。然后，根据单轴加载下的静态和动态测试结果计算比能量吸收（SEA）、补充能量（CE）、归一化能量（NE）和比归一化能量（SNE）。在这种新方法中，NE 和 SNE 的值始终介于 0 和 1 之间。结果表明，通过碰撞泡沫填充管获得的 SEA 应变曲线在静态和动态载荷下呈线性和重叠。然而，动态测试的 NE 曲线是循环的，静态测试中的 NE 曲线是渐近非线性的，并且完全可分离。结果表明，Al、A356 单层、Al-A356 双层和 Al-A356-Al-A356 四层泡沫填充管在动态测试中的 SNE 分别为 0.25、0.29、0.31 和 0.31，而对于静态测试，记录了 0.14、0.15、0.17 和 0.14。发现 CE 和 NE 能量在识别塑性变形和压碎行为方面优于 SEA 能量。
