摘　　要：泡沫金属具有优良的物理性能和综合力学性能,在很多场合都可用作轻质结构材料。在简要介绍该类材料用途的基础上,指出了多向载荷研究对于泡沫金属应用的实际意义,分析了以往工作在该类材料力学性能研究方面的不足,以期推进相关领域的研究者在该方面的突破。在此基础上,提出了一条研究该类材料在多向载荷作用下有关数理关系的思路。Foam metals have excellent physical properties and comprehensive mechanical properties, and can be used as light-weight structural materials in many cases. Based on the brief introduction of the applications of this kind of materials, the practical significance is pointed out to study on the mechanical behavior of foam metals under multiaxial loading for their applications. In addition, the shortcomings of the former work on the mechanical properties are also analyzed for this kind of materials, and it is hoped to push the relevant researchers into breakthrough in this aspeer. On this basis, a thought is also put forward to investigate the mathematical-physical relations of these materials under multi-axial loading.
