The analytical expressions presented in this report relate the crack velocity and the failure time to the surface-layer stress coefficient for compact-tension specimens of Ti-6Al-4V and a 4130 steel subjected to stress-corrosion cracking. The experimental data for the threshold stress intensity factor and the crack velocities for various stress intensity factors agree well with the calculated values.
