Shell Structures in Civil and Mechanical Engineering

Junctions in shell structures: A review

“…Only some monographs contain special chapters or sections in which shell structures composed of regular shell elements joined along the common edges were discussed. Among them let us mention here the books by Flügge [11], Chernykh [12], Baker et al [13], Calladine [14], Bushnell [15], Mikhailovskii [16], Novozhilov et al [17], Bernadou [18], and Zingoni [19].…”

Liquid-containment shells of revolution: A review of recent studies on strength, stability and dynamics

“…Analytical approaches have been very fruitful in investigating the stresses and deformations in shells of revolution within the elastic range [1,2]. The last 10 years have seen the further development of simplified analytical formulations for calculating shell stresses in the vicinity of geometric discontinuities, shell junctions and ring beams, and for evaluating related effects within ring beams.…”

“…Shells are widely used in the civil engineering industry for liquid containment [1,2]. Applications include elevated water tanks, storage vessels for the containment of petroleum products, liquefied gases and industrial chemicals, and water-treatment structures such as settling tanks and sludge digesters.…”

Equatorial bending of an elliptic toroidal shell

“…Novozhilov [1] has called these locations "lines of distortion" in reference to the existence of a bending effect locally disturbing the membrane state of stress in these regions. Discontinuity problems in shells of revolution have been the subject of many investigations, and a good body of closed-form results exists for the more common types of shells and loading conditions [2][3][4][5].…”

“…The performance of containment shells is usually assessed with regard to their stress and deformation response in the linear elastic range [2,3], their vibration characteristics and dynamic response, as well as their nonlinear buckling and postbuckling behaviour within the elastic and plastic ranges of material behaviour. Metal shells are particularly susceptible to buckling on account of their thin-ness (radius-to-thickness ratios typically in excess of 500).…”
