Abstract

Closed-cell cellular materials gained tremendous interest in their application in aerospace, shipbuilding and defence industries due to their exceptional impact energy absorption and lightweight characteristics. To assess the suitability of these materials in practical utilisation, a proper characterisation in dynamic loading is necessary. This paper investigates closed-cell aluminium foam's deformation behaviour due to low-velocity projectile impact in experimentation and finite element analysis. The collapse mechanism was numerically and empirically examined. The experiment and the finite element analysis were found to be in good agreement. The low-velocity projectile impact tests were conducted using an instrumented drop-tower with several projectile tips with an impact energy of 105 J. Finite Element modelling using ABAQUS explicit was undertaken. The results reveal that FE modelling of true foam properties using solid geometry has a good correlation with experimental results. In this study, four impactors/indenters (flat-faced, hemispheric, conical, and truncated-conical) were used. A detailed structural collapse during the low-velocity dynamic impact has been explored with XCT data and finite element tools.

闭孔多孔材料在不同形状弹丸冲击下的变形行为和力学响应

闭孔蜂窝材料由于其特殊的冲击能量吸收和轻量化特性，在航空航天、造船和国防工业中的应用获得了极大的兴趣。为了评估这些材料在实际应用中的适用性，有必要对动态载荷进行适当的表征。本文对闭孔泡沫铝在低速弹丸冲击下的变形特性进行了实验研究和有限元分析。对坍塌机理进行了数值和实证检验。实验结果与有限元分析结果吻合较好。低速弹丸冲击试验采用带有多个弹丸尖的仪器式跌落塔进行，冲击能为105j。结果表明，用固体几何模型模拟泡沫的真实性能与实验结果有较好的相关性。在这项研究中，使用了四种冲击器/压头(平面、半球形、锥形和截锥形)。利用XCT数据和有限元工具对低速动力冲击下的结构崩塌进行了详细的研究。
