项目摘要

Dynamic impacts can cause stress waves within solid materials, resulting in damage to infrastructure, personnel, or devices. However, current approaches to mitigate stress waves are inadequate in that they rely on energy absorption associated with unrecoverable buckling and/or plastic deformation of materials and structures. Moreover, the time required to deform these materials is typically much longer than the time needed for dynamic impacts and stress waves to propagate through these protection materials. Nanofluidics, in which the liquid is forced into nanoscale channels by an external pressure or stress, is expected to attenuate stress waves and offers a entirely new paradigm for the design of protection materials and structures. The overarching goal of this project is to investigate and understand nanofluidics-enabled mitigation of dynamic impacts and stress waves with particular focus on nanofluidics in three-dimensional nanoporous networks. This collaborative project will also provide a broad impact on education including professional trainings to both graduate and undergraduate students, and on outreach including inspiring interactions with local high schools.The objective of this collaborative project is to systematically investigate the science of nanofluidics in non-wetting liquid-solid nanoporous composite materials, and to explore its underlying protection mechanism for mitigating dynamic impacts and stress waves. To this end, the proposed research will focus on three tasks: (i) to investigate and unveil the science of nanofluidics in non-wetting liquid-solid nanoporous structures under a high speed loading using atomistic simulations, (ii) to develop a theoretical model of nanofluidic energy capture mechanism to quantify nanofluidic responses to dynamic impacts and stress waves, and (iii) to design and carry out verification experiments at high strain rates by employing non-wetting liquid-solid nanoporous materials platforms. The nanofluidic energy capture mechanism will refresh existing design strategies of protection materials and structures subjected to stress waves, thereby revolutionizing both fundamental nanofluidics and application technologies.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
动态冲击可能会在固体材料中产生应力波,从而导致基础设施、人员或设备损坏。 然而,目前减轻应力波的方法是不够的,因为它们依赖于与材料和结构的不可恢复的屈曲和/或塑性变形相关联的能量吸收。此外,使这些材料变形所需的时间通常比动态冲击和应力波传播通过这些保护材料所需的时间长得多。 纳米流体,其中液体通过外部压力或应力被迫进入纳米级通道,预计将衰减应力波,并为保护材料和结构的设计提供全新的范例。该项目的总体目标是研究和理解纳米流体能够缓解动态冲击和应力波,特别关注三维纳米多孔网络中的纳米流体。该合作项目还将对教育产生广泛的影响,包括对研究生和本科生的专业培训,以及对外展的影响,包括与当地高中的启发性互动。该合作项目的目标是系统地研究非润湿液固纳米多孔复合材料中的纳米流体科学,并探讨其减缓动力冲击和应力波的潜在保护机制。 为此,拟议的研究将侧重于三项任务:(i)使用原子模拟在高速加载下研究和揭示非润湿液-固纳米多孔结构中的纳米流体科学,(ii)开发纳米流体能量捕获机制的理论模型以量化纳米流体对动态冲击和应力波的响应,以及(iii)通过采用非润湿的液-固纳米多孔材料平台来设计和实施高应变率下的验证实验。该纳米流体能量捕获机制将更新现有的设计策略的保护材料和结构受到应力波,从而彻底改变两个基本的纳米流体和应用技术。这个奖项反映了NSF的法定使命,并已被认为是值得的支持,通过评估使用基金会的知识价值和更广泛的影响审查标准。
