摘要/Abstract

摘要：

提出了一种双材料双箭头负泊松比结构，在保证元胞几何参数不变的前提下，引入了刚性材料分数ψ。采用显式动力有限元软件LS-DYNA对不同冲击速度和不同刚性材料分数下的动力学响应进行数值模拟研究，并详细讨论了其对面内抗冲击能力和能量吸收能力的影响。同时，为了获得较好的综合性能，进一步建立了分层递变梯度模型，探究了梯度形式对峰值冲击力、比吸能、平台应力的影响关系。研究结果表明：刚性材料分数的引入使得平台应力得到了显著提升，并随着刚性材料分数的增加而增加，其对峰值冲击力与比吸能的影响机制有着明显的不同；通过合理地设计梯度分布形式，可以在保持峰值冲击力较低的前提下，进一步提高能量吸收能力，实现对材料吸能过程的控制。

Abstract:

Dual-material auxetic double arrowhead structure with negative Poisson’s ratio was proposed. Under the assumption that all geometric dimensions were the same， the stiff material fraction ψ was introduced. Based on explicit dynamic finite element simulation by LS-DYNA， the in-plane dynamic responses of dual-material auxetic double arrowhead structure with negative Poisson’s ratio were numerically studied. The effects of the stiff material fraction and the impact velocity on the in-plane impact resistance and energy absorption capacities were discussed in detail. In order to obtain better comprehensive performance， a functionally layered honeycomb model was established and the effects of the gradient forms on the peak crush force， specific energy absorption and plat-form stress were investigated. The results show that the platform stress has a great improvement and increases with the fraction of the stiff material， and the influence mechanism on the peak impact force and the specific energy absorption are significantly different from the others. Under the presupposition that the peak impact force was lower， the energy absorption capacity can be improved by reasonable designing gradient forms to realize the control of the energy absorption process.
