项目摘要
This Faculty Early Career Development (CAREER) grant will support fundamental research to understand how porous materials deform and fail under external loading, and to develop predictive models useful for the precise engineering of such materials. Applications are broad and include the safe and sustainable engineering of subsurface operations to extract energy (geothermal), store energy (hydrogen), and dispose of greenhouse gases (carbon dioxide). Still others include the optimal design of components for fuel cells, batteries, and civil infrastructure, all of national interest to the US. Existing models used to predict deformation and failure of microstructurally complex porous materials are slow and contain knowledge gaps that stem from a lack of mechanistic understanding of the physics. This project aims to accelerate computer simulations through novel mathematical algorithms and to anchor the simulations to controlled lab experiments for improved physical understanding. The integrated educational activities include the training of next-generation engineers, curriculum development for graduate students, outreach to K-12 teachers of rural Pennsylvania through a summer research program in partnership with the Center for Science and the Schools at Penn State, and tools and data for domain experts.There is a gap in the fundamental understanding of how porous materials deform and fail at microscopic scales. Classical poromechanical models used to simulate the physics approximate porous materials as continua and, therefore, cannot provide insights into the microscopic origins of failure. Direct numerical simulation presents an attractive alternative but is computationally expensive. This project will support the development of an integrated suite of lab experiments and computational methods with the overarching goal of: (1) enabling a mechanistic understanding of deformation and failure of brittle porous media; and (2) accelerating microscale simulations through physics-informed mathematical approximations. The combined effort will contribute towards establishing structure-property relations that are useful for designing and screening new and resilient microstructures. It will also enable computationally demanding tasks such as optimization and uncertainty quantification associated with geometrically complex porous domains.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.
这笔学院早期职业发展(Career)补助金将支持基础研究,以了解多孔材料在外部载荷下如何变形和失效,并开发对此类材料的精确工程有用的预测模型。应用广泛,包括安全和可持续的地下作业工程,以提取能源(地热)、储存能源(氢)和处置温室气体(二氧化碳)。其他方面还包括燃料电池、电池和民用基础设施组件的优化设计,所有这些都关系到美国的国家利益。现有的用于预测微结构复杂的多孔材料的变形和失效的模型速度很慢,并且存在着由于缺乏对物理学的机理理解而产生的知识空白。该项目旨在通过新的数学算法加速计算机模拟,并将模拟固定在受控实验室实验中,以提高对物理的理解。综合教育活动包括培训下一代工程师,为研究生开发课程,通过与宾夕法尼亚州科学中心和宾夕法尼亚州立大学学校合作的暑期研究项目,向宾夕法尼亚州农村的K-12教师延伸,以及为领域专家提供工具和数据。对多孔材料如何在微观尺度上变形和失效的基本理解存在差距。用来模拟物理上的多孔材料的经典多孔力学模型将多孔材料近似为连续介质,因此不能提供对破坏的微观起源的洞察。直接数值模拟提供了一种有吸引力的替代方案,但计算成本很高。该项目将支持开发一套完整的实验室实验和计算方法,其首要目标是:(1)能够从机理上理解脆性多孔介质的变形和破坏;以及(2)通过物理信息的数学近似来加速微尺度模拟。联合努力将有助于建立有助于设计和筛选新的和有弹性的微观结构的结构-财产关系。它还将实现与几何复杂的多孔域相关的计算要求苛刻的任务,如优化和不确定性量化。该奖项反映了NSF的法定使命,并通过使用基金会的智力优势和更广泛的影响审查标准进行评估,被认为值得支持。
