High speed digital image correlation system for material deformation analyses

点击翻译按钮获取中文摘要

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.
