Digital High-Speed Optical Imaging Facility

University of Toronto, Toronto, Ontario
What the facility does

Capture and investigate catastrophic failure of geological or engineering materials and structures subjected to impacts or blasting loads.

Areas of expertise

Using the Digital High-Speed Optical Imaging Facility, we study the dynamic fracture and impact failure of geological or engineering materials and structure. The infrastructure has the fastest camera in Canada and various optical measurement methods. The application of this research includes earthquake physics, crushability of engineering materials, and fragmentation of rocks by impacts. Dr. Xia has developed several new measurement methods to quantify dynamic strength and fracture properties of rocks and concretes. The research results can be used in blasting-proof design of civilian and defense structures, safety of aerospace structures and automobile, and optimization of blasting in mining and construction etc.
