Abstract: The edge stresses both in flat ribbon layer and inner shell for layered pressure vessel are studied, and them with those in mono-layered shell is contrasted. It is shown that there are no edge stresses but even stresses in flat ribbon layer. Meanwhile, their stresses are independent of each other because of the separation of ribbons from each other (not entirety as a cylinder).
