What is the difference in stress at the junction between a conical shell with folds and a cylinder, compared to the junction between a conical shell without folds and a cylinder?
When the semi-apex angle of the conical shell is large, adding a transition section can reduce the additional local stress at the junction between the conical shell and the cylinder. There shouldn’t be much difference outside the transition section.

In simple terms, structures with folds prevent the welds from overlapping areas of structural discontinuity, thereby reducing stress concentration; this is an advantage over structures without such folds. The lack of folding edges and large taper angles are potential hazard areas, and they are the controlling factors that determine the thickness
