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.

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.

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

Post-critical analysis of torsionally buckled stiffener plates

International Journal of Solids and Structures, 1981
Abstract The determination of the moment-curvature characteristics for stiffened plates buckling away from slender stiffener outstands is seen as an important step towards developing simple engineering approaches to the design problem. The main aspects of a recent programme of research carried out to provide this information on moment-curvature ...

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 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 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,

Stepped Column Critical Buckling Load Estimation

9th International Students Science Congress Proceedings Book
The construction field mainly deals with columns that have two cross-sectional areas, especially in high-height work forms called stepped columns. Standard sections, with varying loads and exact spans, are usually used at different heights to construct the work form. As a result, many accidents happen on construction sites.

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 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 ...
