Bifurcation, limit-point buckling, and dynamic collapse of transversely loaded composite shells
AIAA Journal, 2000The transverse-loading response of laminated composite shell structures is studied experimentally and numerically. Monolithic graphite/epoxy shell structures having layups of [§ 45n/0n]s (n= 1;2;and3) closely represent commercial fuselage structures in both geometry and boundary conditions.

Pre-Limit-Point Buckling of Multilayer Cylindrical Panels Under Pressure
AIAA Journal, 2004motion,7 were observed. The vortex wake expanded for oscillation frequencies less than the Karman frequency, whereas it contracted for frequencies greater than the Karman frequency. The longitudinal spacing decreased significantly with increasing oscillation frequency and changed to a much lesser degree with an increase in the oscillation amplitude. In

The elasto-plastic buckling and postbuckling of imperfect, thin, circular cylindrical shells in axial compression is studied with the use of a mechanism model specifically designed to achieve an accurate representation of the developable polyhedral surface of Yoshimura. The formulation makes it possible to study the influence of asymmetric imperfection

Post-buckling of shallow nano-arches is examined numerically in this study. The small-scale effect is taken into account by using the nonlocal theory. The variational formulation is employed to derive the equilibrium equations of the arch based on the Euler–Bernoulli beam hypothesis.

Dynamic buckling of limit-point systems under step loading
Dynamics and Stability of Systems, 1988The nonlinear dynamic buckling response of discrete systems under step loading of infinite duration is thoroughly discussed by using one-degree-of-freedom models. The analysis is based on the exact nonlinear differential equations of motions and refers to those systems which when subjected to the same loading applied statically exhibit a limit-point ...

A finite element study on bifurcation and limit point buckling of elastic-plastic arches
Computers & Structures, 1996The technique of continuum finite element modeling is used to discretize elastic-plastic circular arches which show nonlinear deformation behavior under external load. Response history curves for different arch models which have the same range angle and thickness, but different radii are updated by using the incremental/iterative procedure.
