Surface oscillations and slow crack growth controlled by creep dynamics of necking instability in a glassy film

Description : We study experimentally the slow growth of a single crack in a glassy film of polycarbonate submitted to uniaxial and constant imposed load. Flame-shaped macroscopic zones of plastic deformation appear at the tips of the crack and the formation of these plastic zones involves a necking instability. ...
