This conference grant will support 30 researchers to attend a workshop that will be held at the University of Minnesota, Minneapolis, tentatively in Fall 2022 or Spring 2023 on mid-scale research infrastructure needs in mesoscale modeling and experimentation. Engineering design is undergoing a revolution sparked by the Materials Genome Initiative (MGI). Instead of making things out of existing off-the-shelf materials, engineers are now exploring ways for designing engineering components at the same time as the materials from which they are made. Advances in cyberinfrastructure and multiscale theoretical and computational materials mechanics frameworks offer pathways to in silico materials and component modeling and design. Yet, in the context of designing strong and damage-tolerant structural metals and products, there are several gaps in realizing the MGI vision, particularly at the critical mesoscale of material microstructure: (1) limited availability and access to high-fidelity experimental and computational datasets, (2) lack of co-design of experiments and modeling, (3) lack of on-demand access to verified and validated (V&V) codes for simulation and experimental analyses, and (4) limited opportunities for workforce training and educational outreach. This workshop will convene to address the feasibility of overcoming these shortcomings, which stifle major innovations in structural materials design, through the creation of a cyberinfrastructure— Knowledgebase of Mesoscale Modeling and Experimentation (KnoMME)—that engages experimental and computational experts in mesoscale plasticity, along with mathematicians and computer scientists with expertise in algorithms, data science and large-scale cyberinfrastructure initiatives.This workshop is a first step toward the vision of the mesoscale mechanics cyberinfrastructure KnoMME to bring together leaders with cross-disciplinary expertise (mechanics, materials science, data science) for a focused dialog on the design and long-term sustainability of such an effort. The intent is for this workshop to lead to a Mid-Scale Research Infrastructure submission to the NSF with aims to: (1) close existing gaps to advance the field of mesoscale modeling and experiments, (2) democratize educational access to materials-design knowledge, and (3) create a sustainable pathway for optimal materials modeling via advanced data-driven approaches. The application context of the workshop will be the infrastructural needs in mesoscale materials mechanics for material design and advanced manufacturing. The expected outcomes of the workshop include: (1) identifying an optimal structure for the KnoMME framework, (2) consolidating strategies for standardizing V&V and uncertainty quantification (UQ) protocols for mesoscale modeling codes, (3) identifying experiments and related software and data that serve as accepted benchmarks for computational codes, and (4) formulating approaches to integrate computational and experimental knowledge for mesoscale modeling of structural metals.This project is jointly funded by the Mechanics of Materials and Structures (MoMS) program in the Division of Civil, Mechanical and Manufacturing Innovation (CMMI) and the Office of the Assistant Director (OAD) in the Directorate for Engineering (ENG).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.

这笔会议拨款将支持 30 名研究人员参加暂定于 2022 年秋季或 2023 年春季在明尼苏达大学举行的研讨会，讨论中尺度建模和实验中的中型研究基础设施需求，工程设计正在经历一场革命。工程师们现在不再用现有的现成材料来制造东西，而是在开发制造工程组件的同时探索如何设计它们。网络基础设施和多尺度理论和计算材料力学框架为计算机材料和组件建模和设计提供了途径，然而，在设计坚固且耐损伤的结构金属和产品方面，在实现 MGI 愿景方面存在一些差距，特别是。在材料微观结构的关键介观尺度上：（1）高保真实验和计算数据集的可用性和访问有限，（2）缺乏实验和建模的共同设计，（3）缺乏对经过验证和验证的按需访问(V&V) 模拟和实验分析代码，以及 (4) 劳动力培训和教育推广机会有限 该研讨会将召开会议，讨论通过创建一个模型来克服这些阻碍结构材料设计重大创新的缺点的可行性。网络基础设施——介观建模和实验知识库（KnoMME）——吸引了介观可塑性方面的实验和计算专家，以及在算法、数据科学和大规模领域拥有专业知识的数学家和计算机科学家网络基础设施倡议。本次研讨会是实现中尺度力学网络基础设施 KnoMME 愿景的第一步，旨在将具有跨学科专业知识（力学、材料科学、数据科学）的领导者聚集在一起，就此类网络基础设施的设计和长期可持续性进行重点对话。本次研讨会的目的是向 NSF 提交一份中尺度研究基础设施，旨在：(1) 缩小现有差距，推进中尺度建模和实验领域，(2) 使教育机会民主化。材料设计知识，(3) 通过先进的数据驱动方法创建最佳材料建模的可持续途径，研讨会的应用背景将是材料设计和先进制造的介观材料力学的基础设施需求。研讨会包括：(1) 确定 KnoMME 框架的最佳结构，(2) 巩固中尺度建模代码的 V&V 和不确定性量化 (UQ) 协议标准化策略，(3) 确定已接受的实验以及相关软件和数据计算代码的基准，以及（4）制定整合结构金属介观建模计算和实验知识的方法。该项目由土木、机械和制造创新部门的材料与结构力学（MoMS）项目联合资助(CMMI) 和工程理事会 (ENG) 助理主任办公室 (OAD)。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进行评估，被认为值得支持标准。
