Buckling and Postbuckling of Prestressed Sandwich Arches

Journal of Structural Engineering, 1993
A nonlinear finite element model is developed to investigate the stability behavior of a novel type of structure, namely prestressed sandwich arch. A prestressed sandwich arch is formed by buckling its individual layers into an arch shape and assembling them as a sandwich composite.

On the Buckling and Postbuckling of Spherical Shells

1984
For the axisymmetric buckling problem of a complete spherical shell we are able to give a complete imperfection sensitivity analysis for the most complicated case to occur, namely that of a double eigenvalue, if we restrict our analysis to nonlinear terms of quadratic order, which is correct mathematically as the bifurcation system turns out to be two ...

Stability, buckling, and postbuckling of elastic structures

Meccanica, 1975
This paper is the continuation of a research on the stability and postbuckling behaviour of elastic structures; in the first Part [n. 4, Vol. X, 1975 of this Journal], the potential energy of elastic tridimensional bodies has been defined in a suitable configuration space, and its properties of regularity have been studied.

Buckling and postbuckling behavior of delaminated sandwich beams

Composite Structures, 1992
Abstract An investigation was performed to study the buckling and postbuckling behavior of sandwich beams containing lengthwise and depthwise through-the-width delaminations. An analytical beam model was developed to predict the buckling load of the beam and to describe its postbuckling response for arbitrarily situated delaminations and various ...

Buckling and postbuckling of stiffened elements with uncertainty

Thin-Walled Structures, 1996
The buckling and postbuckling behaviour of thin-walled stiffened elements under uniform compression with geometric and material uncertainties are examined. The uncertainties in the geometry can arise from tolerances in cold forming, and the ones in material properties result from the uncertain values of the maximum stress at buckling and from the ...

Delamination buckling and postbuckling of composite cylindrical shells

36th Structures, Structural Dynamics and Materials Conference, 1995
A higher-order shear deformation theory is developed for accurately evaluating the transverse shear effects in delamination buckling and postbuckling of cylindrical shells under axial compression. The theory assures an accurate description of displacement field and the satisfaction of stress-free boundary conditions for the delamination problem.

Buckling and postbuckling of thin elliptical anisotropic plates

Computers & Structures, 1993
Summary: The Rayleigh-Ritz method has been used to analyse the buckling and postbuckling behaviour of thin elliptical anisotropic plates. Different layups and ellipse orientations were analysed and compared with finite element results showing good agreement in displacements and total energies in the postbuckled regime.
