Investigation on the Geometric Imperfections driven Local Buckling Onset in Composite Conical Shells
, 2016 Buckling is a critical failure phenomenon for structures, and represents a threat for thin shells subjected to compressive forces. The global buckling load, for a conical structure, depends on the geometry and material properties of the shell, on the ...

Comparison for Different Circumferential Weld-Induced Imperfections on Steel Silos
, 2011 As the thin-walled structure,the buckling of steel silos is very sensitive to the initial geometric imperfections. However, these imperfections are uncertain to the shape and amplitude, so the studies of the initial geometric imperfections have important

Prediction of Buckling and Postbuckling Behaviour of Composite Ship Panels
The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2007 The behavior of ship plating normally depends on a variety of influential factors, namely geometric/material properties, loading characteristics, initial imperfections, boundary conditions and deterioration arising from corrosion and fatigue cracking ...
