Abstract: Buckling at a distinct bifurcation point is more often than not symmetric, in the sense that equal and opposite amplitudes of the single buckling mode give identical physical shapes and hence ...

Abstract: Localization theory for long continuous structures is extended to the buckling of a thin elastic strut supported by a bilinear elastoplastic medium. It is demonstrated that the form of localization ...

Abstract: Recent work on the interactive buckling behavior of compressed sandwich structures (Hunt and Wadee, 1998) is extended to orthotropic core materials. The variation of the material properties can ...

Abstract: A multi-degree-of-freedom nonlinear Rayleigh-Ritz formulation for a sandwich beam is developed and is used to demonstrate the possible sudden destabilizing effects associated with wrinkling on the ...

Abstract: It is proposed that the classical Maxwell criterion for instability of gradient systems has significance as a lower bound on the appearance of localized as opposed to repeated periodic buckling. ...

Abstract: Localized solutions, for the classical problem of the nonlinear strut (elastica) on the linear elastic foundation, are predicted from double-scale analysis, and confirmed from nonlinear volume-preserving ...
