Cumulative Effect Accompanying Large Deformations of a Shell under One-Sided Pressure

摘要

The behavior of a perturbed flat layer of a deformable material under pressure difference is associatedwith the Rayleigh–Taylor instability (see, e.g., [1]). As was shown in [2], the development of instability can lead to the formation of regular fingerlike structures, where the energy and momentum of a thrown layer are cumulated. This effect can be studied separately as well as provide a number of applications. It is somewhat similar to the appearance or special creation of a cumulative jet when throwing a thin layer with the shape of an angle or cone and in other more complicated cases [3].
