Stability of multilayered shells under interlaminar uniformly distributed pressure

The article deals with the problem of the stability of the inner layer of a cylindrical multilayered pipe when uniformly distributed gas pressure acts in the interlaminar gap. The suggested approach takes contact between layers of the shell into account. The article investigates the effect of the divergence angle of the zone of delamination on the form of loss of stability and rigidity of the outer layers of the shell, and on the magnitude of the critical load.Kiev.
