Circular cylindrical shells with nonuniform edge constraints (with zero radial and circumferential displacement) are investigated, including riveted shells. The linear modes of simply supported shells vibrating in vacuo are used as admissible functions, and the solution is obtained with the artificial spring method. The Flugge theory of shells is used and in-plane inertia is retained. Any shell constraint other than simple supports can be studied with the proposed method. Complicating effects due to the contained inviscid fluid, elastic bed of partial axial and angular dimensions, intermediate constraints and added mass are considered. The convergence of the method is numerically investigated and the effect of the number of rivets (clamped arcs) on shell modes is studied. (C) 2000 Academic Press.
