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 ...

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.

Critical Buckling of Delaminated Composite Plates Using Exact Stiffness Analysis

Civil-Comp Proceedings, 2009
The critical buckling of composite plates with through-the-length delaminations is studied using exact stiffness analysis and the Wittrick-Williams algorithm. Computational efficiency is achieved by avoiding discretisation into elements, making the method suitable for preliminary aircraft design. Numerical results for longitudinal, transverse and shear
