CRACK APPROACHING A HOLE

Effects of region of stress concentration ahead of a running crack in Homalite-100 sheets with a centrally located hole were studied by dynamic photoelasticity. Mode I dynamic stress intensity factors and corresponding dynamic strain energy release rates and crack velocities as well as the corresponding Modes I and II static stress intensity factors, static strain energy release rates and strain energy density factors were determined.
