Nonlinear collapse

Part of the Mechanics of Elastic Stability book series (MEST, volume 9)


As has been emphasized already in the discussion of the two-column shallow truss (Figs. 10–14), loss of stability of a shell structure may be due to nonlinear collapse (“snap-through”) or to bifurcation buckling. The purpose of this section is to present many examples in which the failure mode is nonlinear collapse. Examples are given of axisymmetric collapse of elastic-plastic-creeping monocoque cylinders under axial compression and ring-stiffened cylinders under external hydrostatic pressure, of general collapse of curved and straight pipes under uniform bending, of cylindrical shells and panels with concentrated loads and cutouts, and of noncircular cylinders under axial compression. The chapter closes with an example of axisymmetric collapse of an axially compressed complex rocket interstage. The collapse is caused by a local load path eccentricity that gives rise to concentrated bending and local plastic flow.
