2nd Int. Conference on Buckling and Postbuckling Behaviour of Composite Laminated Shell Structures Braunschweig, Germany, 5-7 September 2008, demonstrating results from the EU project COCOMAT, www.cocomat.de. Topics New achievements in the following topics of buckling, postbuckling and collapse
Many theoretical and experimental studies have been performed on buckling and postbuckling behavior of flat stiffened composite panels (see for example Refs.3-5). Recently, a wide body of description and detailed data on buckling and postbuckling tests has been compiled [6] (see chaps.12-14). However, studies on
Postbuckling, Collapse, Composites, Simulation tools, Experiments, Aircraft application BENCHMARK 3 Description of the panel Benchmark 3 is an axially compressed stiffened CFRP panel depicted in Figure 1. The panel consists of a . the linear buckling analysis in general all codes can be employed. To obtain the first buckling load of the
DIC is used to capture buckling and post-buckling behavior of large composite panel subjected to compressive loads DIC is ideal for capturing buckling modes & resulting out-of-plane displacements Provides very useful insight in the transition regime from local skin buckling to global buckling of panel
post-buckling conditions. The results without considering any kind of imperfection, are closed and in good agreement with the tests in terms of buckling and post-buckling stiffness, as well as of collapse loads. Jiang et al. [13] studied the buckling of panels subjected to compressive stress using the differential quardrature element method.
numerical post-buckling critical load is more conservative than that obtained in physical tests [4,5,6].Typical load-shorting of stiffened structure undergoing buckling and post-buckling response are shown in Figure 3 where corresponding simplifications have been overlaid indicating the k1 pre-buckling, k2 post-buckling, k3 collapse
The aim of this work is to present and discuss the results of an ongoing numerical investigation on the buckling, post-buckling, collapse and DSM design of two-span lipped channel beams.The numerical results presented were obtained through (i) GBT buckling analyses and (ii) elastic and elastic-plastic shell finite element (SFE) post-

in stringer-stiffened shells because the postbuckling zone slope becomes less. As a result more instability is observed(see Figs. 6 and 7). Fig. 4.

for the in-plane buckling of arches where the effect of extension of the centerline is included and for the lateral buckling of an I-beam where warping restraint is considered. The oldest analysis of buckling, Euler's work on a perfect elastic column, (see Timoshenko and Gere (1961)) included a postbuckling analysis.
postbuckling and collapse. Under compression, these structures experience buckling, adopt specific mode shapes and develop a wide range of damage mechanisms, which under further compression into the deep postbuckling region can lead to the collapse of the structure. The work presented in this thesis was mainly focused on three objectives.
