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.

该会议补助金将支持30名研究人员参加将于2022年秋季或2023年春季在明尼苏达大学明尼阿波利斯分校举行的研讨会，讨论中尺度建模和实验中的中尺度研究基础设施需求。工程设计正在经历一场由材料基因组计划（MGI）引发的革命。工程师们不再使用现有的现成材料，而是在探索设计工程部件的同时设计制造材料的方法。网络基础设施和多尺度理论和计算材料力学框架的进步为硅材料和组件建模和设计提供了途径。然而，在设计坚固和耐损伤的结构金属和产品的背景下，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中尺度上：（1）有限的可用性和访问高保真实验和计算数据集，（2）缺乏实验和建模的协同设计，（3）缺乏按需访问用于模拟和实验分析的验证和确认（V V）代码，以及（4）有限的劳动力培训和教育推广机会。本次研讨会将讨论克服这些缺点的可行性，这些缺点扼杀了结构材料设计中的重大创新，通过创建一个网络基础设施-中尺度建模和实验知识库（KnoMME）-使中尺度塑性的实验和计算专家参与，沿着数学家和具有算法专业知识的计算机科学家，数据科学和大规模网络基础设施倡议。本次研讨会是迈向中尺度力学网络基础设施KnoMME愿景的第一步，将具有跨学科专业知识的领导者聚集在一起（力学，材料科学，数据科学），就这种努力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提交中型研究基础设施，旨在：（1）缩小现有差距，推进中尺度建模和实验领域，（2）使材料设计知识的教育普及化，（3）通过先进的数据驱动方法为最佳材料建模创建可持续的途径。研讨会的应用背景将是材料设计和先进制造的中尺度材料力学的基础设施需求。研讨会的预期成果包括：（1）确定KnoMME框架的最佳结构，（2）巩固&中尺度模拟代码的标准化VV和不确定性量化（UQ）协议的战略，（3）确定可作为计算代码公认基准的实验和相关软件和数据，以及（4）制定方法，将计算和实验知识结合起来，用于结构金属的细观模拟。本项目由土木工程系材料与结构力学（MoMS）项目联合资助，该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
