Abstract The principal innovation of this proposal is that DIC is envisioned as theprimary strain measuring technique in a large-scale structural testing facility. This non-contacting technique yields a fully quantifiable strain field in two or three dimensions bymanipulating digital images. This emerging technology has not yet been harnessed for thestudy of civil engineering structures.The acquisition of these instruments, when coupled with current renovation of laboratoryspace within the Division of Engineering, will provide a versatile structural testing facility that willsupport a coordinated effort between faculty and students in Civil and EnvironmentalEngineering, Mechanical Engineering, and Mathematics. The diverse, yet well-linked expertiseof the senior personnel enables a broad range of research that includes structural steel, timber,reinforced concrete, fiber-reinforced polymer (FRP) materials, corrugated paper containers, andthe transient stresses in sport equipment.The structural testing request consists of hydraulic equipment, data acquisitioninstruments, signal conditioning devices, shop tools, and various transducers. The resulting structural testing facility will serve as a blueprint of versatile, cost effective,and nimble laboratory design for other small undergraduate institutions, by building thefacility from industrial components.The pedagogical value of the DIC technique as an aid to visual understanding inscience, mathematics, and engineering will be disseminated through publication andconferences.Initially, the DIC technique will be used in six engineering courses. As new researchareas are explored with the requested facilities, it is anticipated that six additionalengineering courses may benefit.The diverse talents of the research team offer the potential to extend these newtechniques into disciplines outside of engineering.

本文的主要创新之处在于，DIC被设想为大型结构试验设备中的主要应变测量技术。这种非接触式技术通过处理数字图像在二维或三维中产生完全可量化的应变场。这一新兴技术还没有被用于土木工程结构的研究。这些仪器的获得，再加上目前工程系内实验室空间的改造，将提供一个多功能的结构测试设施，支持土木与环境工程、机械工程和数学系师生之间的协调努力。高级人员的多样而又紧密联系的专业知识使其能够进行广泛的研究，包括结构钢，木材，钢筋混凝土，纤维增强聚合物（FRP）材料，瓦楞纸容器和运动器材中的瞬态应力。结构测试要求包括液压设备，数据采集仪器，信号调节设备，车间工具和各种传感器。由此产生的结构测试设施将作为一个多功能的，成本效益高，灵活的实验室设计的蓝图，为其他小型本科院校，通过建立thefilion从工业组件。DIC技术的教学价值，作为一种辅助视觉理解科学，数学和工程将通过出版物和会议传播。最初，DIC技术将用于六个工程课程。随着新的研究领域的探索与所要求的设施，预计六个额外的工程课程可能会受益。研究团队的多元化人才提供了将这些新技术扩展到工程以外的学科的潜力。
