This grant provides financial support for the workshop entitled "Uncertainty Quantification in Computational Modeling of Materials", to be held on January 17-18, 2019 at Johns Hopkins University in Baltimore, MD. It is widely known that the performance of materials is strongly influenced by uncertainties associated with composition, constituent properties, and micro- or meso-structure. This is especially true as materials undergo large irreversible deformations, approaching failure through fracture or fatigue. Computational modeling of such behavior is further complicated by uncertainties in material models (e.g., uncertainty due to incomplete physics), and lack of data to quantify material micro- or meso-structure and property distributions. The computational cost of uncertainty analyses is an additional challenge. The aim of this 2-day thematic workshop is to bring together prominent scholars in solid and structural mechanics, materials science, and applied mathematics with a shared interest in uncertainty quantification and computational materials modeling to showcase the state-of-the-art, collectively identify existing and future challenges, and promote innovative ideas in the field. Emphasis has been being placed on bringing together experts in seemingly disparate fields who face shared challenges related to uncertainty quantification and materials, but who otherwise have only limited opportunities to interact. Funding from this grant will support travel costs for 10 students/postdoctoral researchers to attend the workshop and present their work during a poster session as well as production of a report and a review journal article on the state of the field. In this two-day workshop, 29 invited leading experts in uncertainty quantification and materials modeling from across academia, government, and industry will present ongoing and future challenges related to uncertainty quantification facing the computational mechanics, applied mathematics, and materials science communities. The workshop will be comprised of 7, 2-hour sessions in a single technical track with each track having four presentations and a 20-minute discussion period. With each session covering a different topic, this unique format is intended to foster discussion around the most important technical challenges in each topic and avenues for their solution. The workshop will also feature a poster session where students/postdocs have the opportunity to share their work. The outcome of these presentations and discussions will be documented in a final report and a full-length review journal article discussing the themes of the workshop. These two documents will be widely disseminated to the research community and beyond.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.

这笔赠款为题为“材料计算建模中的不确定性量化”的研讨会提供财政支持，该研讨会将于 2019 年 1 月 17 日至 18 日在马里兰州巴尔的摩约翰霍普金斯大学举行。众所周知，材料的性能受到与成分、成分特性以及微观或细观结构相关的不确定性的强烈影响。当材料经历较大的不可逆变形，通过断裂或疲劳接近失效时尤其如此。由于材料模型的不确定性（例如，由于不完整的物理学而导致的不确定性）以及缺乏量化材料微观或细观结构和属性分布的数据，这种行为的计算建模变得更加复杂。不确定性分析的计算成本是另一个挑战。这个为期 2 天的主题研讨会的目的是汇集固体力学和结构力学、材料科学和应用数学领域的杰出学者，他们对不确定性量化和计算材料建模有共同的兴趣，共同展示最先进的技术确定现有和未来的挑战，并促进该领域的创新理念。 重点是将看似不同领域的专家聚集在一起，他们面临着与不确定性量化和材料相关的共同挑战，但除此之外，他们的互动机会有限。这笔赠款的资金将用于支付 10 名学生/博士后研究人员参加研讨会的旅费，并在海报会议上展示他们的工作，以及制作一份关于该领域现状的报告和评论期刊文章。在这个为期两天的研讨会上，来自学术界、政府和工业界的 29 位受邀的不确定性量化和材料建模领域的顶尖专家将介绍计算力学、应用数学和材料科学界面临的与不确定性量化相关的当前和未来挑战。该研讨会将由 7 个各 2 小时的会议组成，每个会议有 4 场演讲和 20 分钟的讨论时间。每场会议都涵盖不同的主题，这种独特的形式旨在促进围绕每个主题中最重要的技术挑战及其解决方案的讨论。研讨会还将举办海报会议，学生/博士后有机会分享他们的工作。这些演示和讨论的结果将记录在最终报告和讨论研讨会主题的全文评论期刊文章中。这两份文件将广泛传播给研究界及其他领域。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
