Fractoluminescence characterization of the energy dissipated during fast fracture of glass
Abstract
Fractoluminescence experiments are performed on two kinds of silicate glasses. All the light spectra collected during dynamic fracture reveal a black body radiator behaviour, which is interpreted as a crack velocity-dependent temperature rise close to the crack tip. Crack velocities are estimated to be of the order of 1300 m.s-1 and fracture process zones are shown to extend over a few nanometers.
