WebThe effect of the stiffening rings are introduced by approximating the varying thickness/ plate radius by a Fourier series. Numerical examples are illustrated for non-stiffened plates of two thicknesses and two stiffened plates, with one and two stiffening rings respectively, all under clamped-edge boundary condition.

WebInstead, there is a requirement that the longitudinal stiffeners should satisfy a certain minimum stiffness requirement. This may give a reasonably proportioned stiffened plate, but it reduces the freedom to produce the most desirable structure. The longitudinal stiffeners in a plate with more than three stiffeners behave like compression
