| 摘 要： | 由于泡沫铝合金具有可压缩性，经典的Taylor理论模型已不适用于描述该类材料。在适当假设的基础上建立了泡沫铝合金Taylor撞击实验分析的理论模型，并利用Taylor撞击实验数据验证了该模型的有效性，研究了泡沫铝合金的动态力学特性。实验结果表明，所考察的泡沫铝合金的应变率敏感性不强。

| Abstract: | Considering the compressibility of an aluminum-alloy foam and the unavailability of the classic Taylor model to it,a theoretical model used to analyze the Taylor impact experiment of the aluminum-alloy foam was proposed based on some assumptions.The Taylor impact experiment was performed to validate the proposed model and to explore the dynamic mechanical properties of the aluminum-alloy foam.The experimental results show that the strain-rate sensitivity of the studied aluminum-alloy foam is not strong. |

| Keywords: | solid mechanics Taylor model dynamic impact aluminum-alloy foam mechanical properties |
