Full-Field Measurement Of Contact-Point And Crack-Tip Deformations In Soda-Lime Glass. Part Ii: Stress Wave Loading

This second of a two part paper demonstrates the applicability of DGS for the problems under stress wave loading conditions. Ultra high-speed photography (1m frames/sec) in conjunction with DGS and a Hopkinson pressure bar to load soda-lime glass specimens are employed. The optical measurements are post-processed to obtain relevant engineering parameters and stress field near dynamically loaded crack-tip, both while stationary and during propagation.
