Abstract: Stiffening by means of an elastic core is demonstrated to increase significantly the resistance of a cylindrical shell to buckling from an external impulsive pressure. Both theory and experiments ...

Abstract: Comparisons between an unknown-but-bounded imperfection model and a random imperfection model show that for simple pointwise failure measures, at least, the two models give the same expressions ...

Abstract: Control of uncertain imperfections by means of convex bounds on finite Fourier transforms is shown to be more direct and not as overly conservative as control based on uniform bounds, i.e., ...

Abstract: This paper shows that when very thin cylindrical shells are subjected to an external impulsive pressure, the interaction between the radial, purely extensional mode and the flexural modes is ...

Abstract: Experiments are presented which demonstrate the statistical nature of the buckling of thin strips under very high axial compression. Probability distributions of wavelengths determined theoretically ...

Abstract: An analysis is presented for stress amplification in a ring caused by the dynamic instability of symmetric in-and-out breathing oscillations, which results in energy transfer to flexural modes. ...

Abstract: The formation of small, flexural wrinkles in the walls of a sandwich shell under uniform radial impulse is examined. A buckling criterion based on the magnifications of initial wall imperfections ...

Abstract: Buckling of thin cylindrical shells from axial impact is studied under the assumption that initial imperfections can be approximated by “white noise.” Linear small-deflection theory is used to ...

Abstract: A large deflection, elastic-plastic numerical theory (SABOR/DRASTIC 6) is used to investigate dynamic buckling motion beyond strain-rate reversal in cylindrical shells under radial impulse. It is ...
