Buckling Loads of Columns with Varying Cross Sections

Journal of Engineering Mechanics - ASCE, 1989
A new numerical method is presented for evaluating the buckling loads of columns with varying cross sections. By this method, the traditional eigenvalue problem is transformed into a special initial value problem, and the buckling loads of the columns can be evaluated by an iteration procedure, which is to satisfy the boundary conditions specified in ...

Buckling and Post-buckling Characteristics of Pressure-Loaded Cylinders

Journal of Applied Mechanics, 1993
Nonlinear Ritz analysis is used to investigate the elastic buckling behavior of pressure loaded cylinders. Careful analysis of the energy changes during the buckling process allows definition of a reduced stiffness theoretical model. This reduced stiffness model provides a convenient means for estimating lower bounds to the imperfection sensitive ...

Buckling of Eccentrically Loaded Carbon Nanotubes

Solid State Phenomena, 2017
In the present study, buckling of eccentrically loaded nanobeams in which the load is not applied at the centroid of cross section, has been studied. Eringen’s Nonlocal Elasticity Theory has been used in the formulation of governing equation of motion of the nanobeam.

Buckling of Shear Loading Plates with Strengthenings

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2000
AbstractThe paper treats the influence of either weakening or strengthening of rectangular plates on the critical external buckling load. The plate geometry was chosen so that the buckling process takes place in the elastic range. The simply supported plate is loaded with shear forces per unit length which act on its edges.

Experimental Buckling Loads of Water‐Loaded Beams

Journal of Structural Engineering, 1986
This note reports results of two tests performed on full-scale thin-walled prestressed concrete beams where the increase in external load is caused by changing the water level contained in the beam section. The purpose of the experiments was to contrast experimental values of the buckling load with predictions based on a numerical model of the problem,

Buckling load for nonuniform columns

Computers & Structures, 1977
Abstract A method to determine an approximate lower bound buckling load for a nonuniform column is presented. The method is applicable to both hinged-hinged and cantilever columns. A finite difference scheme is used to represent the equilibrium equation for the column.

Experimental Investigation of Buckling of Hydrostatically Loaded, Conical Shells and Practical Evaluation of the Buckling Load

1982
An extensive experimental investigation of buckling of conical shells that are supported only along their lower edge and that are loaded by the weight of a liquid leads to diagrams and formulas which can be used directly in the design of such shells.

Buckling of geometrically imperfect cylindrical shells — definition of a buckling load

International Journal of Non-Linear Mechanics, 2002
On the basis of extensive buckling tests and analytical and numerical buckling analyses for composite cylinders it became desirable to provide a recommendation for the most reliable evaluation of stability limits for imperfect CFRP cylinders subjected to axial compression.

Buckling Loads of Nonuniform Columns

Journal of the Structural Division, 1969
Using finite-difference method, the buckling problem of a hinged-hinged column is expressed as a linear algebraic eigenvalue problem. An iterative procedure to evaluate accurately the minimum eigenvalue of the involved coefficient matrix, without recourse to the characteristic equation or inversion of the matrix, is presented. By the method of Rayleigh
