Popis:	The extension of the kinetics theory of thermally activated crack propagation to the analysis of non-steady state conditions leads to a series of n homogeneous linear first order differential equations. The theory is applied to Regions I and II of stress corrosion cracking, controlled by the cyclically repeating two-step consecutive energy barrier system of corrosion reaction and bond breaking. For the model the system of n differential equations representing the crack tip concentration distribution is reduced to three expressions. The analysis provides a means by which the existence and the duration of the transition state can be determined, a necessary information for both steady state and for high frequency stress corrosion fatigue tests.
