Crushing Analysis of Rotationally Symmetric Plastic Shells

摘要

The crushing analysis of rotationally symmetric plastic shells undergoing very large deflections is presented. A general methodology is developed and simple closed form solutions which can be useful for practical applications are derived for the case of a conical shell and a spherical shell under point load, a spherical shell crushed between rigid plates and under boss loading, and a spherical cap under external uniform pressure. The effect of the end conditions and the limitations of this approach are discussed in detail. (Author)
