Asymmetric Behavior of a Sloping Spherical Shell under finite Deflections

摘要

The current status of the theory and applications of calculating thin-wall constructions makes it possible to determine the stress-strain states of elastic shells of various shapes that are in equilibrium under external loads with an accuracy sufficient for engineering practice. This statement is true both for small deflections of shells and for finite and large deflections when the behavior of shells is described in various nonlinear mathematical models. The status of calculations of the stability of elastic shells is distinctly different. The same mathematical models considerably overestimate measured critical loads, and advanced skills are required to determine the critical loads with sufficient accuracy by semiempirical methods. This situation is most clear for well-studied elastic spherical shells.
