| 摘 要： | 将铝板塑性加工成半球孔层金属结构薄层,以此为基本单元按一定方式连接形成球形孔多孔金属,研究了孔结构对球形孔多孔金属性能的影响.结果表明,平板层相连的球形孔结构,使其强度高于同样条件下堆积的空心金属球结构.这种新型球形孔多孔金属的强度较高,能够有效地吸收能量,铝板的厚度和孔隙率对其压缩和能量吸能性能有明显的影响.

| Abstract: | A novel method to prepare metallic structure with hemisphere layer formed by metal sheet plastic processing and connect it to novel porous metal in certain ways is proposed. The strength of structure composed of interconnected flat plate layers is greater than that of structure composed of accumulative metallic balls with air core in the same condition. This structure has high strength and can absorb energy, and the thickness and porosity of aluminum sheet have obvious effect on its compressive property. |

| Keywords: | metallic materials punch porous metal porosity compression and energy absorption spherical pore |
