The modes of collapse of a rigid-plastic circular cylindrical shell subjected to centrally applied, opposed point loads in which the deformation is not confined to the vicinity of the loaded points are analysed. It is shown that the solution is analogous to that of an equivalent beam-foundation problem and the analogy is discussed. The results are compared with observations made during a series of experiments concerned with the crushing of aluminium tubes by opposed indenters.
