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 ...

A Model for the Nonlinear Buckling of Human Aorta

Volume 4: Dynamics, Control and Uncertainty, Parts A and B, 2012
Human aortas are subjected to large mechanical stresses due to blood flow pressurization and through contact with the surrounding tissue. It is essential that the aorta does not lose stability by buckling for its proper functioning to ensure proper blood flow. A refined reduced-order bifurcation analysis model is employed to examine the stability of an

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.
