Nonlinear Dynamic Buckling of Sandwich Panels

Journal of Applied Mechanics, 1976
Nonlinear dynamic buckling of simply supported rectangular sandwich panels with isotropic cores and with initial curvature under transverse loads is analyzed. The large deflection sandwich panel equations proposed by Reissner are solved using a trigonometric series spacewise and by Houbolt scheme for timewise integration.

Nonlinear Buckling and Stability of Cylindrical Panels

SIAM Journal on Mathematical Analysis, 1979
The problem of the buckling of a simply supported thin, elastic, cylindrical panel subjected to a uniform axial compression is studied by constructive methods. In the case of “narrow” panels we obtain near the classical buckling load $\lambda _1 $ a description of all stable and unstable buckled states which branch from the unbuckled state at $\lambda ...

Nonlinear Vibration of Buckled Beams

Journal of Engineering for Industry, 1972
The steady state response and stability of free and forced vibration of simply supported, axially restrained, buckled beams is investigated. The equations of motion dealing with the buckled state include the effect of an initial displacement either by initial load or by initial temperature. By an assumed mode solution, the response and stability of two

Nonlinear buckling analysis of composite shells

15th Structural Dynamics and Materials Conference, 1974
An incremental finite element procedure is presented for nonlinear buckling (collapse) analysis of composite shells undergoing large elastic deformations. The type of element employed is a modified version of Clough-Felippa's quadrilateral shell element. The element is made of any number of rigidly bonded orthotropic layers of different thicknesses and

Buckling and geometrically nonlinear analysis of sandwich structures

International Journal of Mechanical Sciences, 2015
Abstract In this work a finite element model is presented for buckling and nonlinear analysis of multilayer sandwich plates and shells, with a soft core sandwiched between stiff elastic layers. The finite element is obtained by assembling all element-layers through the thickness using specific assumptions on the displacement continuity at the ...

Nonlinear Asymmetric Buckling of Truncated Spherical Shells

Journal of Applied Mechanics, 1970
This paper is concerned with the theoretical study of buckling of truncated spherical shells. Sander’s nonlinear equations for deep shells are used and the equations of equilibrium are expressed in terms of displacements for spherical shells. Based on these equations, analyses are made for calculating prebuckling axisymmetric equilibrium positions and ...

Nonlinear Isometric Bifurcation and Shell Buckling

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1977
AbstractA simple concept for studying the lower stability limit of shell structures which is based on the theory of isometric transformation of surfaces is outlined. The influence of imperfection on the lower stability limit is discussed in the case of axially compressed cylindrical shells.

Nonlinear Cyclic Behavior of Reinforcing Bars Including Buckling

Journal of Structural Engineering, 1992
The effects of inelastic buckling on monotonic and cyclic behavior of reinforcing steel bars are studied. Experimental tests show that this phenomenon occurs when the ratio between length and diameter of the bar exceeds 5, and that it leads to a postyield softening branch in compression that strongly influences the cyclic behavior of the bar.

Buckling and Nonlinear Analysis of Conoidal Shells

Volume 8: 28th Conference on Mechanical Vibration and Noise, 2016
Slender shell structures described by ruled surfaces have been frequently used in civil engineering and, among these slender shells, conoidal shells are frequently favored as roofing units to cover large column-free areas due to their ease of construction, aesthetic value and structural efficiency. This work studies the nonlinear post-buckling behavior
