How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
This paper is a study of snap-through properties of a non-linear dynamic buckling response to sinusoidal excitation of shallow spherical shells. The highly non-linear motion of snap-through and its effects on the overall vibration response has been studied. Sinusoidal wave generators (oscillators) produce a sine wave of constant amplitude and frequ...
The behavior of spherical caps under radial dynamic edge loading in theform of step loading of infinite duration in the time domain has beeninvestigated. The aim here is to present a mathematical model of shallowshells of revolution which may undergo snap-through buckling as a resultof the radial displacement of the circular boundary. The snap-thro...
The present study has involved the development of a mathematical and numerical model of shallow shells of revolution which may possibly undergo snap-through buckling. For the numerical solution of the problem a computer program, using a linearized finite element incremental-iterative approach based on updated Lagrangian formulation and solution str...
In this study, the snap-through buckling behaviour of axisymmetric shells, subjected to axisymmetric horizontal peripheral load or displacement for various shell parameters and various boundary conditions, is investigated. Results obtained seem not to have been reported previously. An application of peripheral displacement type of loading is seen i...
