How Drillstring Rotation Affects Critical Buckling Load?
IADC/SPE Drilling Conference, 2008Abstract Buckling of tubulars inside wellbores has been the subject of many researches and articles in the past. However, these conservative theories have always followed the same assumptions: the wellbore has a perfect and unrealistic geometry (vertical, horizontal, deviated, curved), the friction and rotation effects are ignored ...

Critical buckling load of pile in liquefied soil
Soil Dynamics and Earthquake Engineering, 2020Buckling 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 Buckling Loads for Tapered Columns
Transactions of the American Society of Civil Engineers, 1962Formulas 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, 2006Abstract 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

Approximate Derivation of Critical Buckling Load
Journal of Architectural Engineering, 2009This paper proposes an approximate derivation for the critical buckling load of a column, based on the application of a uniformly loaded beam's midspan moment and deflection to the buckled column's rotational equilibrium. The curvature of a pin-ended member, when it buckles under axial load, is similar to the curvature assumed by the same member when ...

Safely Exceeding the "Critical Buckling Load" in Highly Deviated Holes
SPE Offshore Europe, 1989Abstract The critical buckling load, developed by Dawson and Paslay, is generally accepted as the limiting criteria for pushing tubing into a highly deviated hole. This criteria severely limits the distance coiled tubing can be pushed into a highly deviated hole.

Determination of critical buckling loads with Gröbner bases
Computers & Structures, 1995Abstract Grobner bases and the related Buchberger algorithm offer an elegant computational environment for the triangularization/solution of systems of few polynomial equations together with modern computer algebra systems. Here this approach is applied to the geometrically nonlinear structural analysis of columns and the critical buckling loads of ...
