| dc.description.abstract-en | Fractography on fractured K-IC specimens of spheroidized steel has revealed a statistical distribution of dimple sizes (in the ductile failure region) dependent on the temperature and distance from the pre-crack tip. The statistical distributions of carbide sizes and dimple sizes conform closely to a Weibull distribution. The size parameter of the statistical distribution of dimples increases with the distance from the pre-crack tip, but diminishes as the temperature rises. The shape parameter declines as the distance from the pre-crack tip increases, but grows with the test temperature. The experimental findings have confirmed a probabilistic theory of void nucleation ahead of the pre-crack tip. The dimple density on the fracture surface at a certain distance from the pre-crack tip corresponds to the density per unit area of carbides multiplied by the probability of void nucleation. | en |
