Workshop: Towards Rigorous Verification & Validation of Predictive Computational Models in Mechanics of Materials; New York, New York; July 27, 2018

该基金将为2018年7月27日在纽约举行的题为“迈向材料力学预测计算模型的严格验证和验证”的研讨会提供资金支持。随着预测计算建模在减少新机械结构、材料系统和制造技术的时间和成本方面的作用不断增强，作为建模过程一部分的验证和验证（V&amp；V）的伴随使用并没有跟上步伐。验证确保计算模型准确地表示底层数学模型及其解决方案，而验证确定计算模型在模型的预期范围内表示物理现实的程度。因此，V&amp；V在维持预测模型的可行性和优势方面是至关重要的，这反过来又促进了美国的国家安全和经济竞争力，并有可能改善生活质量、健康和社会福祉。在本次研讨会中，将讨论通过V&amp；V促进更准确和先进的预测建模和仿真的途径。预计它还将成为促进来自利益攸关方社区的建模人员和实验人员之间改进的、有意义的合作的途径。这项奖助金将用于计划活动、制作报告和受邀参加者的旅行。在这个为期一天的研讨会上，材料力学、材料科学与工程、制造、数学和相关学科的主要专家将在一个互动的环境中聚集在一起，讨论如何促进预测模型在广泛的实验验证（和数学验证）方面取得重大进展，并为具体的可操作的下一步提供建议。目的是让这些战术建议开始激励社区，并为未来的努力提供阶段性点。该项目的成果还将包括对知识和工具开发的建议，预计不仅为从业者，而且为学生、博士后研究人员和教育工作者提供机会。所有的调查结果都将收录在一份最终报告中，该报告将在学术界、政府和工业界传播。

This grant provides financial support for the workshop entitled: Towards Rigorous Verification & Validation of Predictive Computational Models in Mechanics of Materials to be held on July 27, 2018 in New York, New York. As the role of predictive computational modeling for reducing time and cost of new mechanical structures, materials systems, and manufacturing technologies continues to grow, the concomitant use of verification and validation (V&V) as part of the modeling process has not kept pace. Verification ensures that the computational model accurately represents the underlying mathematical model and its solution, whereas validation determines the degree to which the computational model represents physical reality within the intended scope of the model. Therefore, V&V is a crucial cog in maintaining the viability and advantages of predictive modeling, which in turn advances U.S. national security and economic competitiveness, and potentially improves the quality of life, health, and well-being of the society. In this workshop, pathways that facilitate more accurate and advanced predictive modeling and simulation through V&V will be discussed. It is also expected that it will serve as the avenue to foster improved, meaningful collaborations among modelers and experimentalists from the stakeholder communities. Funding from this grant will support planning activities, production of a report, and travel of invited participants.In this one-day workshop, leading experts in the mechanics of materials, materials science and engineering, manufacturing, mathematics, and related disciplines will convene in an interactive setting to discuss ways to stimulate strong progress towards widespread experimental validation (and mathematical verification) of predictive models and to provide recommendations for specific actionable next steps. The intent is for these tactical recommendations to start galvanizing the community, and provide staging points for future efforts. Outcomes of the project will also include recommendations for knowledge and tool development that are expected to provide opportunities not only for practitioners, but also for students, postdoctoral researchers, and educators. All findings will be captured in a final report that will be disseminated across academia, government, and industry.
