MRI: Acquisition of Optical Interferometry System for Multi-Scale Analysis of Surface Characteristics for Civil Engineering Applications

该主要研究仪器(MRI)的研究目标是通过使用先进的研究设备和分析方法，将表面分析融入土木工程应用中。在土木工程中，表面纹理对系统响应的重要影响已被认识到，但研究一直是有限的，因此需要基础研究来开发用于表面表征的测量、分析和实现工具。该仪器(光学干涉仪)将用于使用多种标度和方法进行基本表面分析，这是首次确定表面纹理或将其与大多数测试材料的工程性能相关联。将制定表面分析指南。将为生产经过处理的天然材料和制造符合所需表面特性的合成材料提供建议。将在土木工程系统的建模方面取得进展，并将获得独特的表面知识。如果成功，这项研究将通过利用产生的重要新知识量化表面特征，提高对与工程应用相关的力学和微观力学的基本理解。通过综合实验和数值分析，将有可能在多种材料的界面行为、纤维夹杂物以及使用前、使用中和使用后的分析和取证方面取得重大进展。拟议的仪器将增加广泛的研究能力；为推进正在进行的研究和促进新的研究提供机会；为研究基础设施增加独特的能力以吸引外部资金；并促进部门间和部门内的合作。拟议的活动将为不同的教职员工和学生提供研究培训机会；吸引代表性较低的群体(女性、第一代学院学生和西班牙裔学生，他们在加州大学保利的学生群体中占很大比例)进入工程学；将最先进的研究整合到学习模块中，供加州大学保利学院(与美国S大学最大的一些本科工程系)、其他美国大学和国际机构使用。

The research objective of this Major Research Instrumentation (MRI) proposes to incorporate surface analysis to civil engineering applications through the use of advanced research equipment and analysis methods. Fundamental research is required to develop measurement, analyses, and implementation tools for surface characterization in civil engineering, where the significant effects of surface texture on system response has been recognized, yet research has been limited. The instrumentation (optical interferometer) will be used to conduct fundamental surface analyses using multiple scales and approaches, representing the first time that surface texture will be determined or correlated to engineering performance for the majority of the test materials. Guidelines will be developed for surface analysis. Recommendations will be provided for production of processed natural materials and manufacture of synthetic materials for desired surface characteristics. Advancements will be enabled in modeling of civil engineering systems with unique surface knowledge that will be obtained. If successful, the research will improve fundamental understanding of mechanics and micromechanics associated with engineering applications through quantifying surface characteristics with significant new knowledge generated. Significant advancements will be possible in the analysis of interface behavior, fiber inclusions, and pre-, in-, and post-service analyses and forensics for a wide variety of materials through integrated experimental and numerical analyses. The proposed instrumentation will add extensive research capabilities; provide opportunities for advancing ongoing research and enabling new research; add unique capabilities to the research infrastructure to attract external funding; and foster inter- and intra-department collaborations. The proposed activities will provide research training opportunities for a diverse group of faculty and students; attract underrepresented groups (female, first-generation college, and Hispanic students, who constitute a significant percentage of the Cal Poly student body) to engineering; and integration of state-of-the-art research into learning modules for use at Cal Poly (with some of the U.S.?s largest undergraduate engineering departments), other U.S. universities, and internationally.
