项目摘要

Louisiana State University (LSU) and Louisiana Tech University (LA Tech) have established the Industry-University Cooperative Research Center (IUCRC) for Innovations in Structural Integrity Assurance (CISIA). Structural integrity and reliable life prediction of infrastructure and mechanical components have relevance in every public and private sector, including but not limited to energy, aerospace, construction, manufacturing and infrastructure. CISIA will serve as a trusted source of transformative insights, predictive capabilities, and materials innovations across broad industrial sectors, focusing on structural integrity assurance for small and large structures and mechanical components. CISIA will conduct use-driven, fundamental, pre-competitive research to establish linkages between material properties and infrastructure performance in terms of its structural integrity. The Center will elucidate and translate these links and their collective impact on reliability across all U.S. industrial sectors. The academic and industrial members of CISIA will work in concert to produce a diverse workforce of engineers who are trained in state-of-the-art facilities to utilize modern methods of structural health monitoring and analysis. These engineers will become a highly qualified and productive workforce that enhances the global competitiveness and resilience of U.S. industries. Structural health monitoring, diagnosis, and in-situ rehabilitation of aging civil and industrial infrastructure are critical for public safety and economic development. Understanding, controlling, and improving the mechanical integrity of near-surface regions of mechanical components subject to high-stress/high-cycle contact (interfacial solid-solid and solid-fluid conjunctions) are fundamental problems affecting U.S. manufacturing and defense industries. The LSU site focuses on structural integrity and materials innovation—with emphasis on multiscale materials characterization/testing and multiscale physics-based modeling/simulation to understand component fatigue, wear, lifetime assessment, and non-destructive accelerated testing. By integrating validated diagnostics, machine learning, and data-driven decision making, CISIA will elucidate and translate the links between new materials, manufacturing processes, service histories, and their collective impact on reliability across all U.S. industrial sectors. Establishing linkages between material properties, infrastructure performance, and structural integrity requires multi-disciplinary research collaborations. The members of this proposed IUCRC have the requisite multi-disciplinary expertise, history of collaboration, proximity to a broad and strategic national manufacturing corridor, and access to the necessary research infrastructure to produce scientific advances in the structural integrity field, accelerated by the proposed industrial partnership.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.

路易斯安那州立大学（LSU）和路易斯安那理工大学（LA Tech）建立了结构完整性保证创新（CISIA）的产学合作研究中心（IUCRC）。基础设施和机械部件的结构完整性和可靠寿命预测与每个公共和私营部门都有关系，包括但不限于能源、航空航天、建筑、制造和基础设施。CISIA将成为广泛工业领域变革性见解、预测能力和材料创新的可靠来源，专注于小型和大型结构和机械部件的结构完整性保证。CISIA将开展以使用为导向的基础性竞争前研究，以在结构完整性方面建立材料属性与基础设施性能之间的联系。该中心将阐明和翻译这些联系及其对美国所有工业部门可靠性的集体影响。CSIA的学术和工业成员将协同工作，培养一支多样化的工程师队伍，他们在最先进的设施中接受培训，利用现代结构健康监测和分析方法。这些工程师将成为高素质和高生产力的劳动力，提高美国工业的全球竞争力和弹性。老化民用和工业基础设施的结构健康监测、诊断和原位修复对于公共安全和经济发展至关重要。了解、控制和改善机械部件近表面区域的机械完整性是影响美国制造业和国防工业的根本问题。LSU网站专注于结构完整性和材料创新，重点是多尺度材料表征/测试和基于物理的多尺度建模/模拟，以了解组件疲劳，磨损，寿命评估和非破坏性加速测试。通过整合经过验证的诊断、机器学习和数据驱动的决策，CISIA将阐明和解释新材料、制造工艺、服务历史之间的联系，以及它们对美国所有工业部门可靠性的集体影响。建立材料性能，基础设施性能和结构完整性之间的联系需要多学科的研究合作。这个拟议的IUCRC的成员具有必要的多学科专业知识，合作历史，接近广泛的战略性国家制造走廊，并获得必要的研究基础设施，以在结构完整性领域取得科学进步，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。
