Approximate Derivation of Critical Buckling Load

Journal of Architectural Engineering, 2009
This 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 ...

Critical Local Buckling Conditions for Deepwater Pipelines

Volume 4: Terry Jones Pipeline Technology; Ocean Space Utilization; CFD and VIV Symposium, 2006
In many deepwater pipeline applications, a clear understanding of pipe local buckling behaviour due to excessive bending and/or external pressure is required to adequately design subsea pipeline systems to an acceptable degree of risk. With ultra-deepwater pipelines being considered for water depths of nearly 3000 m, pipe collapse, in many instances ...

Research on the Critical Buckling Strain Criterion for Pipelines

2008 7th International Pipeline Conference, Volume 3, 2008
The local buckling of pipelines is regarded as a kind of failure. The critical buckling strain is an important parameter in strain-based design of pipelines. According to the grey system theory, the factors affecting the critical buckling strain were analyzed and the correlation between these factors and the critical buckling strain was quantitatively ...

Critical Buckling Pressure and Buckling Shape of Composite Cylindrical Shell Subjected to Hydrostatic Pressure

2018 OCEANS - MTS/IEEE Kobe Techno-Oceans (OTO), 2018
This paper is devoted to the buckling behavior of the composite cylindrical shell subjected to hydrostatic pressure. Both critical buckling pressure and buckling shape are taken into account in the paper. The critical buckling pressure has been calculated using analytic formulas and validated by finite element method. The influence of type of materials,

Safely Exceeding the "Critical Buckling Load" in Highly Deviated Holes

SPE Offshore Europe, 1989
Abstract 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, 1995
Abstract 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 ...

Critical Velocity for Collapse of Viscoplastic Cylindrical Shells Without Buckling

Journal of Applied Mechanics, 1977
Successful operation of many practical devices that involve high-speed implosion of shells of circular cross section requires a stable collapse motion. In this paper, the dynamic buckling of imploding viscoplastic cylindrical shells is analyzed, and critical velocities are determined for which amplification factors of initial departures from ...

Critical Buckling Load on Large Spherical Shells

Journal of the Structural Division, 1962
Approximate evaluation for watertanks, hortonspheres, vapor containers, containment vessels for nuclear reactors, and so forth, has been computed, taking into account out-of-roundness and local flattened areas; graphs have been plotted giving critical buckling load as function of maximum radial deviation over average chord to flattened area.

Critical Scaling and Prediction of Snap-Through Buckling

2017
We examined predictability of catastrophic events in snap-through buckling. In our study, we applied load at the center of an elastic arch and monitored the fundamental frequency by hammering. We found that the frequency goes to zero as the load approaches the critical value (load limit point), suggesting that the occurrence of the snap-through ...

Critical buckling strains of round tubes in flexure

International Journal of Mechanical Sciences, 1979
Abstract The results of a series of 11 tests on single and two span circular hollow tubular beams are used to compare with inelastic bending and axial compression theories of buckling. Predictions of critical strain from both analyses exceed the values obtained from the experimental results, the bending critical stress being somewhat higher than that
