Asymptotic Analysis of the Static and Dynamic Buckling of a Column with Cubic - Quintic Nonlinearity Stressed by a Step Load

A. M. Ette, J. U. Chukwuchekwa, I. U. Udo–Akpan & W. I. Osuji · Journal of Advances in Mathematics and Computer Science · 2019

In this paper, the static and dynamic buckling loads of a viscously damped imperfect finite column lying on an elastic foundation with cubic – quintic nonlinearity but trapped by a step load (in the dynamic case) is investigated analytically. The main objective is to determine an...

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...

Perturbation Approach in the Dynamic Buckling of a Model Structure with a Cubic-quintic Nonlinearity Subjected to an Explicitly Time Dependent Slowly Varying Load

A. M. Ette, I. U. Udo-Akpan, J. U. Chukwuchekwa, A. C. Osuji & M. F. Noah · Journal of Advances in Mathematics and Computer Science · 2019

This investigation is concerned with analytically determining the dynamic buckling load of an imperfect cubic-quintic nonlinear elastic model structure struck by an explicitly time-dependent but slowly varying load that is continuously decreasing in magnitude. A multi-timing regu...
