为研究泡沫铝复合结构对应力波的防护能力,利用传统和改进的分离式霍普金森压杆(SHPB)装置对不同相对密度及不同厚度组合的泡沫铝-铝板复合结构进行冲击试验。研究结果表明:泡沫铝作为夹层,可使入射波分多次传到背板,延迟应力波到达时间,降低了应力波强度。随着泡沫铝夹层厚度的增加,应力波衰减效果明显。泡沫铝-铝板复合结构作为面板,应力波的加载方式发生变化,上升沿得到改善,脉冲宽度增大,最大应力幅值降低,同时吸收大量冲击能,是一种良好的应力波防护材料。增大复合结构中泡沫铝厚度,应力波的上升沿时间延长、斜率减小,应力幅值降低,但脉冲宽度变化不大;铝板厚度对应力波传播影响较小。随着泡沫铝相对密度的增加,经泡沫铝-铝板复合结构作用后,应力波的上升斜率减小,最大应力幅值降低,但脉冲宽度和上升沿时间不变。

利用Taylor杆冲击实验与数值模拟方法研究了Ti-5553钛合金在高应变率冲击下的动态行为。Ti-5553合金在两种热处理工艺处理后获得了不同准静态力学性能的等轴组织和双态组织。在泰勒杆冲击实验的基础上,应用ANSYS/LS-DYNA有限元分析软件研究了材料参数屈服强度值σs和失效应变值εf的变化对Taylor杆冲击能量、速度、加速度等过程参量和冲击结果的影响,将σs值设定为1 170-1 400 MPa,εf设定为0.1-0.8.研究结果表明：屈服强度值的变化对冲击前后能量、速度、加速度的改变量影响较小。随着屈服强度值的增大,冲击过程中能量、速度、加速度的变化速率有所增加,冲击后试样的应变量减小;失效应变值的变化对冲击过程量有明显影响;对等轴组织钛合金,εf〈0.7时,随着失效应变值的增大,能量、速度、加速度的变化速率逐渐增大,试样冲击后几乎无回弹现象;当εf≥0.7时,过程参量曲线全部重合,试样冲击后有明显回弹现象;当设定εf=0.75和εf=0.35时,等轴组织和双态组织钛合金分别符合真实Taylor杆冲击变形特征。

目前国际学界有两类生态足迹模型,即以Wackernagel为代表的经典模型和Bicknell为代表的投入产出模型。研究以2002年江苏省经济为例,依照Bicknell的投入产出模型思路,采取Ferng的改良计算方法,对江苏经济的需求、进口、出口以及积累各项的生态性土地占用及化石能源地占用做出一一估算。综合两种模型的优缺点,调整了足迹结果,转换成以全球标杆衡量的虚拟土地,以评估江苏这样的开放型经济区域的可持续发展能力。结果显示:(1)江苏人均地区生态足迹实际高达2.33hm2,真实生态赤字率高达58.8%,可持续能力堪忧;(2)江苏通过国内外贸易实现了0.009hm2的生产性土地顺差和0.068hm2的化石能源地逆差,贸易方式总体属于生态逆差型。最后,引入足迹影响力与足迹感应力的概念,研究生态足迹的产业波及效果,结果显示江苏二产部门的足迹感应力系数最强,其未来发展也将面临较大的生态瓶颈。
