Stability of axially loaded tapered columns/Centriškai gniuždomų trapecinių kolonų stabilumas

open access: yesJournal of Civil Engineering and Management, 2000
In this paper, theoretical analysis of tapered column's bearing capacity is presented. A slender axially loaded column loses stability, when it achieves critical load (1). Critical load for uniform column can be calculated using L. Euler's formula (3).

On Euler’s decomposition formula for $$q$$ q MZVs [PDF]

open access: yesThe Ramanujan Journal, 2014
In this short and elementary note we derive a q-generalization of Euler's decomposition formula for the qMZVs recently introduced by Y. Ohno, J. Okuda, and W. Zudilin. This answers a question posed by these authors in [10].

Buckling in columns. Solution of the indeterminations of Euler's theory and derivation of an equation for inelastic buckling

open access: yesResults in Engineering, 2023
Buckling in columns under central load has always been a complex problem and until now remains unclear. This work consists of two parts. In the first, a theory is presented to solve the indeterminations of Euler's theory, such as: Moment, slope ...

Inverse hyperbolic equation, Spectral technique, Regularization method, Operational matrix

open access: yesKuwait Journal of Science
Recently, the realm related to Euler's Beta function has played a significant role in the development of special function theory. In this study, a new extension of the special function known as Euler's Beta function with respect to the Mittag-Leffler ...

Light, Gravity and Matter (with emphasis on thermo-gravity waves) [PDF]

open access: yesINCAS Bulletin
What are light, gravity, and regenerating matter? Where do they originate and where do they go? The answers to these questions lie in one of the most powerful equations ever discovered: Euler's formula (i.e., complex analysis).

Evaluating a double integral using Euler's method and Richardson extrapolation

open access: yesLietuvos Matematikos Rinkinys
We transform a double integral into a second-order initial value problem, which we solve using Euler's method and Richardson extrapolation. For an example we consider, we achieve accuracy close to machine precision (~10-13).

General dual Euler-Simpson formulae [PDF]

open access: yesJournal of Mathematical Inequalities, 2008
We consider a general dual Simpson formulae, using some Euler-type identities. A number of inequalities, for functions whose derivatives are either functions of bounded variation or Lipschitzian functions or $R$-integrable functions, are proved.

Theoretical calculation method of hyperbolic rotating thin shell bending problem

open access: yesZhongguo Jianchuan Yanjiu
ObjectiveIn order to analyze the bending characteristics of a hyperbolic rotating thin shell, the complex two-dimensional mechanical problem is simplified into a one-dimensional bending problem based on Euler's Bernoulli beam theory.

Comparative investigation, numerical modeling, and buckling analysis of one-way reinforced concrete wall panels

open access: yesResults in Engineering, 2022
This paper presents a comparative study on the Reinforced Concrete (RC) wall design equations for one-way action panels given in the ACI 318–19, Eurocode 2, Australian standards (AS 3600), British standards (BS 8110–1:1997), and other proposed equations ...
