Measurements of Impact-Induced Fracto-Emission from Soda-Lime Glass and Simultaneous Observation of the Cracking Process by High-Speed Photography

In order to study the fracto-emission mechanism, measurements of impact-induced fracto-emission (FE) of negatively charged particles from a soda-lime silicate glass were conducted at different impact energies, with simultaneous observation of the fracture mode by high-speed photography. The FE signa...
