| Abstract: | A fatigue crack can be effectively retarded by heating a spot near the crack tip under nil remote
stress condition. The subcritical spot heating at a proper position modifies the crack growth behaviour in a way, more or less, similar to specimen subjected to overload spike. It is observed that the extent of crack growth retardation increases with increasing level of overload as well as with increasing spot temperature. It is also observed that modification in crack growth behaviour is a function of location of heating spot and
maximum retardation is observed at + 5 position. |
