As a strength parameter less dependent on loading conditions, crack initiation stress is suggested to be used as a lower limit for spalling strength. So far, no suggested methods are given by the ISRM to determine crack initiation stress. In order to understand the physical meaning of the various methods and determine this characteristic stress threshold accurately, we compared the similarities and differences between these methods and then analyzed their applicable scope. It is suggested that a comprehensive consideration be taken to select an appropriate method to identify the crack initiation of rocks in compression.
