| Abstract: | In this paper fatigue crack growth retardation due to overloading and spot heating (to a sub critical temperature) ahead of crack tip have been addressed. The wheeler model for crack growth retardation has been used for the purpose of comparison. The shaping exponents ‘m’ of both the cases were numerically determined from experimental data and variations in the result have been analysed. It is found that shaping exponent ‘m’ due to spot heating at specific position is more than that due to overload |
