For more than a century, engineers have chased new ways to turn the planet’s natural motions into usable power, from tides to geothermal heat. Now a small group of physicists says Earth’s own magnetic ...

Eggs come out shell-free with chef's simple countertop-cracking method Los Angeles-area restaurateur and chef Andrew Gruel demonstrates a flat-surface cracking technique and finger grip that helps ...

The dynamic response of cylindrical sandwich shells with aluminum foam cores subjected to air blast loading was investigated numerically in this paper. According to KNR theory, the nonlinear ...

In physics, on seeking for a deeper understanding of a topic we often formulate simple questions which, though not realizable in practice, should be satisfactorily answered. For instance, what exactly ...

Abstract: Transfer matrix method is employed to analyze the natural frequencies and natural modes of circular cylindrical shells in this paper. Using the Flugge shell theory, which is more accurate ...

Deep-sea pressure structures, including submersibles, deep-sea space stations and delivery platforms, underwater gliders, subsea pipelines, ocean platforms, electronic cabins, etc., play an important ...

ABSTRACT: The static buckling load of an imperfect circular cylindrical shell is here determined asymptotically with the assumption that the normal displacement can be expanded in a double Fourier ...
