it’s mechanical character of opening hole is much more complicate than the one in column shell.By finite element analysis
the impact of the semi-cone angle on the stress concentration factor of opening hole is analyzed.It is found that the greater the deflection angle of the hole
leading to greater stress concentration factor.And on this basis
the impact of the size of conical shell opening hole a/R on the stress concentration coefficient are investigated.The impact of the change of strengthened fence’s length on stress concentration coeffient is analyzed.It indicates that the fence is an effective method to strengthen the conical shell opening hole.
