Dynamic Buckling Load of an Imperfect Viscously Damped Spherical Cap Stressed by a Step Load

G. E. Ozoigbo, E. Nwaeze & M. Okpala · Physical Science International Journal · 2015

This paper determines the dynamic buckling load of a lightly and viscously damped imperfect spherical cap with a step load. The spherical cap is discretized into a pre-buckling symmetric mode and a buckling mode that consists of axisymmetric and non-axisymmetric buckling modes. T...

On the Buckling Modes and Buckling Load of an Infinitely Long but Harmonically Imperfect Column Lying on Cubic – Quintic Foundation

A. M. Ette, J. U. Chukwuchekwa, W. I. Osuji & G. E. Ozoigbo · Asian Research Journal of Mathematics · 2018

This paper utilizes perturbation and asymptotic techniques to discuss and obtain, analytically, the buckling modes and buckling load of a harmonically imperfect column lying on an elastic foundation that has cubic – quintic nonlinearity. Two slightly different approaches are here...
