NSF funding is requested for a three-day workshop on nanometer and sub-micrometer scale effects on strength and plasticity of metals. The workshop will highlight dramatic increases in plastic strength as sample size and/or microstructural scale decreases to sub-micron and even nanometer scales. This includes experimental and computational investigations of sub-micron compression samples, bulk samples with nanometer-scale grain size, and multilayer thin film composite materials with nanometer-scale phases. The reported phenomena are not explained by crystal or strain gradient plasticity theories. Thus, an objective of the workshop is to assess and critically evaluate these observations and the corresponding theories and computational approaches to understand them.The societal benefits are international in scope, involve both junior and senior participants in the materials/mechanics communities, and extend to nanotechnology developers and users. Specifically, this workshop provides a needed forum to guide and advance the international research community at a scope not possible in a traditional conference. The requested funding will enable US participation by 4 senior and 4 junior (Ph.D. received within the last 6 years) researchers of the highest caliber, plus 3 to 4 highly capable graduate students and/or under-represented individuals. Up to 70 participants will be accommodated. Results will be disseminated through written summaries provided by workshop moderators, web-based streaming of presentations and/or capture of presentation slides, and workshop discussion groups hosted by graduate students at their home institutions.

NSF资金要求进行为期三天的纳米和亚微米尺度对金属强度和可塑性的影响。 随着样本量和/或微结构尺度降低到亚微米甚至纳米尺度，车间将突出显示塑料强度的急剧增加。 这包括对亚微米压缩样品的实验和计算研究，具有纳米尺寸晶粒尺寸的散装样品以及具有纳米尺度相的多层薄膜复合材料。 报道的现象未通过晶体或应变梯度可塑性理论来解释。 因此，研讨会的一个目的是评估和批判性评估这些观察结果以及相应的理论和计算方法来理解它们。社会福利在范围内是国际性的，涉及材料/力学社区的初级和高级参与者，并扩展到纳米技术开发商和用户。 具体来说，该研讨会提供了一个必要的论坛，以指导和推进国际研究界的范围。 要求的资金将使我们能够由最高才能的4名高级和4名大三学生（在过去6年内获得博士学位），外加3至4位强大的研究生和/或代表性不足的人。 最多容纳70名参与者。结果将通过研讨会主持人提供的书面摘要，基于Web的演示文稿和/或捕获演示幻灯片以及由研究生在其家庭机构主持的研讨会讨论小组来传播。
