| Abstract: | The determination of critical crack size is the key point in fracture dynamics,but this is certainly difficult for low-carbon steel.This article offers a method for low-carbon steel plates,which can be used to calculate the crack extended life of drawn wing panels of components,such as I-beam,box beam etc.,and then provides basically scientific basis for the management of metal structure. |
