The finite element analysis of stress concentration factor for the V-notch on the inner surface of cylindrical shell

This paper builds the three-dimensional finite element model of the single axial V-shaped groove on inner surface of cylindrical shell. It is obtained the influences laws of the stress concentration factor affected by the dimensionless quantities of the geometric configuration of the cylindrical shell and the groove by analyzing numerical simulation results. The function expression of the stress concentration factor Kt is fitted to provide a valuable reference for the calculation of the stress concentration factor for the V-notch on the inner surface of cylindrical shell.
