Critical buckling load of pile in liquefied soil

Soil Dynamics and Earthquake Engineering, 2020
Buckling instability has been recently identified as a possible mechanism of pile failure in liquefiable deposits and this failure mechanism is not explicitly mentioned in most design codes. To carry out routine design and checking, it is necessary to reliably estimate the critical buckling load of pile for a given liquefiable site.

Critical upheaval buckling forces of imperfect pipelines

Applied Ocean Research, 2014
Abstract A buried pipeline may have upheaval buckling when it works in high temperature and high pressure (HT/HP) conditions. The upheaval buckling behavior is sensitive to initial structural imperfections. There have already been some approximation formulas of critical axial forces for some particular shape imperfections. However, these formulas did

Critical Force in the Buckling of Drill Bits

Journal of Applied Mechanics, 1979
We consider a fourth-order nonlinear system of differential equations that describe the slope of a steadily rotating flexible rod, one end of which is clamped, and the other end of which is “hinged.” There is a force directed along the length of the rod.

Critical Buckling Pressure of Veins

ASME 2008 Summer Bioengineering Conference, Parts A and B, 2008
Vein tortuosity is often seen as a consequence of venous hypertension and chronic venous disease. However, the underlying mechanism of vein tortuosity is unclear. The aim of this study was to test the hypothesis that hypertensive pressure causes vein buckling that leads to tortuous veins. We determined the buckling pressure of porcine jugular veins and

The Critical Buckling Pressure of Arteries

ASME 2007 Summer Bioengineering Conference, 2007
Artery stability is essential to normal arterial functions. This study examined the critical internal pressure at which arteries buckle. The critical pressure was found to be strongly related to the axial strain in the arteries.

The Effect Of Shear Deformation On The Critical Buckling Of Columns

Journal of Sound and Vibration, 1994
Summary: Starting from equations analogous to those that are widely used for vibration of axially loaded Timoshenko beams, insights are obtained into the buckling behaviour of columns which deform in shear. These insights help in explaining and recognizing those combinations of end conditions for which a simple formula, originally derived by Engesser ...

Buckling of a critically tapered rod: global bifurcation

Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2003
The present paper, which can be considered as a continuation of the first author's previous papers [\textit{C. A. Stuart}, J. Math. Pures Appl., IX. Sér. 80, No. 3, 281--337 (2001; Zbl 1056.74019) and Proc. R. Soc. Edinb., Sect. A, Math. 132, No. 3, 729--764 (2002; Zbl 1020.34076)] is concerned with studying the buckling of a tapered rod. This physical

Buckling of the Circular Plate Beyond the Critical Thrust

Journal of Applied Mechanics, 1942
Abstract In this paper a complete mathematical solution of the problem of the buckling with large deflections of a thin circular plate under uniform radial pressure is given, assuming radial symmetry. Buckling takes place as soon as the prescribed thrust pe at the edge reaches a certain critical value pE.

Critical Buckling Loads for Tapered Columns

Transactions of the American Society of Civil Engineers, 1962
Formulas and graphs for determination of critical elastic buckling loads of uniformly tapered columns having wide flange section, box section, and other cross-sectional shapes are presented; columns with pinned ends, fixed-free ends, fixed-pinned ends, and fixed ends are considered; critical elastic buckling loads may be obtained directly from graphs ...

Stiffness and critical buckling load of perforated sheeting

Thin-Walled Structures, 2006
Abstract This paper deals with selected foundations of the design of perforated trapezoidal sheeting. Based on numerical analysis, graphs on effective stiffness values for perforated sheeting with different arrays of holes are provided. As an outlook on further research, the calculation of the buckling coefficient for a perforated plate under uniform
