High speed digital image correlation system for material deformation analyses

拟议的NSERC RTI应用程序所请求的支持将用于购买高速数字图像相关(DIC)系统。该装置将被广泛用于目前由申请人的NSERC发现基金支持的研究项目中，以研究新的能量耗散结构。此外，该设备还将用于研究材料在高应变率下的变形和结构在高速测试条件下的响应的联合申请者。这种高速摄像机还将用于生物力学分析。使用该系统分析的实际工程结构包括但不限于泡沫填充编织管、切割变形的铝型材、高强度钢板和锂离子电池的电极表面。生物力学分析将包括量化软组织相对于骨骼的运动，以及记录冲击波在冲击条件下通过上肢和下肢的传播。

The requested support from the proposed NSERC RTI application will be used to purchase a high speed digital image correlation (DIC) system. This device will be used extensively in the research program currently supported by the applicant's NSERC Discovery Grant to study novel energy dissipation structures. Additionally, this equipment will also be used by the co-applicants investigating materials deformation at elevated strain rates and response of structures under high speed testing conditions. The high speed camera will also be used in biomechanical analyses. Practical engineering structures which will be analyzed with this system include, but are not limited to, foam filled braided tubes, aluminum extrusions subjected to cutting deformation, high strength steel sheet metal, and electrode surfaces in lithium-ion batteries. Biomechanical analyses will include the quantification of soft tissue motion relative to bone and the documentation of shockwave propagation through the upper and lower extremities under impact conditions.
