Abstract:
This article discusses the influence of micro -gold phase tissue of the welding head and its effect on the growth rate of fatigue cracks. It uses the fissure expansion rate data of the standard sample. Considering the influence of micro -tissue, the fatigue model of fatigue cracks in different regions is used to prepare computer programs to estimate the expansion of the crack. Compared with the experimental value.
