Buckling of Viscoelastic Columns. Part I: Constant Load Buckling

Rubber Chemistry and Technology, 1985
Abstract The constant load buckling of viscoelastic columns has been studied extensively in the past and equations have been derived to predict the buckling time from the geometry of the columns and the constitutive equation of the material. These theories restrict themselves to columns loaded with an axial load only.

Extrapolation Techniques for Buckling Loads

Journal of Structural Engineering, 1983
The southwell, modified and massey extrapolation techniques are derived for a doubly symmetric beam with a transverse force applied at an eccentricity to the shear center. A finite element algorithm which takes into account small initial geometric imperfections is presented using simple matrix algebra. The load vs deflection path for elastic cases, can

Bounding of Frame Buckling Loads

Journal of the Structural Division, 1970
Frame stability calculations are recast into the form of a low order, nonlinear eigenvlaue problem. It is shown that at each stage of the iterative solution of the problem, upper and lower bounds on the sway buckling load are established. The conditions needed for convergence and bounding are examined and verified by several numerical problems.

Buckling Loads for Stepped Columns

Journal of the Structural Division, 1964
The formulation of exact characteristic buckling load equations for ideal stepped columns is shown. The method is based on the three-step moment equation. This expression, analogous to the well-known three-moment equation, relates the bending moments at three adjacent steps of a slightly buckled column.

Secondary Buckling of Compression-Loaded Composite Plates

AIAA Journal, 1996
The phenomenon is described of secondary buckling in plates that are clamped along the loaded edges and simply supported and stiffened along the adjacent unloaded edges. An experiment is described that is used to study secondary buckling of plates with these boundary conditions.

Buckling Load of a Stepped Column

Journal of the Aeronautical Sciences, 1951
A procedure is developed for computing the critical buckling load of a column having a finite number of steps with constant EI within each step. The procedure is applicable to columns with any end conditions and with loads applied within the span, as well as at the ends.

Buckling Loads of Columns with Varying Cross Sections

Journal of Engineering Mechanics, 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 ...

Both Bounds to Buckling Loads and Fundamental Frequencies

Journal of Applied Mechanics, 1994
A simple procedure for improving the Krylov-Bogolyubov-Weinstein-Isaacson-Keller (KBWIK) lower bound and the Rayleigh upper bound to the first eigenvalue is described and illustrated by examples. The procedure makes use of the method of successive approximations, the Rayleigh-Schwarz quotients, the Krylov-Bogolyubov enclosure theorem, and the Temple ...

Design sensitivity analysis of non-linear buckling load

Computational Mechanics, 1988
This paper describes three procedures for calculating design derivatives of the nonlinear critical load. Constraints on the critical load arise naturally in optimal design of structures having nonlinear behavior. The incremental procedures used for nonlinear analysis can fail before reaching the final load level due to buckling or collapse of the ...
