Creep buckling of nonlinear viscoelastic columns

Acta Mechanica, 1986
Creep buckling of columns is analyzed for materials obeying nonlinear single memory integral constitutive laws. There have been two basic methods to analyze creep buckling of columns; the Rabotnov and Shesterikov's linearized dynamical approach and Hoff's quasistatic nonlinear approach, the former predicts critical buckling loads and the latter yields ...

Nonlinear Buckling of Composite Shells of Revolution

Journal of Aerospace Engineering, 2002
By adopting the energy method, a method of calculating the stability of the rotational composite shell is presented that takes into account the influence of nonlinear prebuckling deformations and stresses on the buckling of the shell. The relationships between the prebuckling deformations and strains are calculated by nonlinear Karman equations.

Buckling of Sheathed Walls: Nonlinear Analysis

Journal of Structural Engineering, 1988
A nonlinear theory for analyzing the buckling behavior of sheathed walls is presented. The theory predicts that the reversal of lateral deflection occurs when the load is applied near the compression center of the wall. This phenomenon is due to the movement of the compression center caused by the nonlinear joint stiffness.

Nonlinear Axisymmetric Buckled States of Shallow Spherical Caps

SIAM Journal on Mathematical Analysis, 1975
Nonlinear axisymmetric buckled states of a thin, elastic spherical cap satisfying edge conditions for which the spherical shape remains one possible state of equilibrium when the cap is subjected to a uniform radial load are studied by constructive methods.

Improved nonlinear buckling analysis of structures

Computational Mechanics, 1990
The theory of structural stability is both an important and a difficult subject, whose main field of application is found in the design of thin wall lightweight structures and shells. It is unavoidable to employ nonlinear model and to use finite element numerical method in order to obtain the critical load under the action of which the instability of ...

ASYMPTOTIC INVESTIGATION OF BUCKLED BEAM NONLINEAR VIBRATION

2012
This article presents the application of a modern analytical approach on the nonlinear vibration of buckled beam with generalized deadzone discontinuity and proposes a novel identical function (IF) for the nonlinearity. The powerful analytical method called Parameter Expansion Method (PEM) is used to obtain the exact solution of dynamic behavior of the

Structural optimization for specified nonlinear buckling load factor

Japan Journal of Industrial and Applied Mathematics, 2002
Optimal design of finite-dimensional elastic structures is considered. The proposed method is based on the sensitivity analysis where the sensitivity formulation is written in general form for coincidental buckling load factors including limit points and bifurcation points.
