Popis:	Based on former studies this paper deals with both the front shape variation of nozzle corner cracks and the calculation of crack propagation rates. An approximate method describing fatigue crack growth at nozzle corners under cyclic internal pressure is proposed here. The results calculated are compared with those reported in the literature. The good agreement shows that the views proposed here are effective and may be valuable for the researchers in this field.
