A summary is first presented of the conceptual difficulties and paradoxes surrounding plastic bifurcation buckling analysis. Briefly discussed are nonconservativeness, loading rate during buckling, and the discrepancy of buckling predictions with use of .I2 flow theory vs JZ deformation theory. The axisymmetric prebuckling analysis, including large deflections, elastic-plastic material behavior...

in this paper, dynamic analysis of the composite truncated sandwich conical shells (stcs) with various boundary conditions subjected to low velocity impact was studied analytically, based on higher order sandwich panel theory. impact was assumed to occur normally over to the top face-sheet and the contact force history is predicted using two solution models of the motion are derived based on ha...

Abstract This paper uncovers new manifestations of the homoclinic snaking mechanism in post-buckling regime a pressurized thin cylindrical shell under axial load. These forms tend to propagate either wholly or partially direction that is orthogonal applied load and so, unlike earlier Woods & Champneys (1999, Heteroclinic tangles unfolding degenerate Hamiltonian Hopf bifurcation. Phys. D, 12...

One cannot assume that resemblances between the mechanical devices of human technology and those produced by the evolutionary process reflect either specific copying of nature by people or some particular point of functional superiority. A third alternative is that the two mechanical contexts derive quite different advantages from a given arrangement. While this latter might appear unlikely, on...
