Buckling of Stiffened Thin Walled Cylindrical Shells due to Global Shear
Thin walled cylindrical shells are important components of industrial structures such as liquid storage tanks, silos, etc. Shell buckling is usually a major failure mode of thin walled shells under extreme loads such as earthquakes. Longitudinal and radial stiffeners are generally used in order to increase buckling capacity of thin walled shells. During an earthquake, cylindrical shells may exp...
متن کاملBuckling of Cylindrical Steel Shells with Random Imperfections due to Global Shear
This study aims to investigate the effects of geometric imperfections on buckling of thin cylindrical shells due to global shear. To this end, more than 320 finite element models of cylindrical shells with different diameter to thickness ratios were prepared. Random imperfections with different amplitudes were applied to numerical models. The results revealed that global buckling of cylindrical...
متن کاملAcoustic coupling to membrane waves on elastic shells
The interaction of an acoustic field with a smooth thin shell in a fluid is described by the superposition ofa background field plus membrane waves on the shell. The former is defined by a local impedance condition, which accounts for the inertia of the shell, but takes no account of the in-surface, membrane effects. The shell's flexural stiffness tums out to be of secondary importance. The bul...
متن کاملSound radiation from nested cylindrical shells
ABSTRACT Fluid-loaded nested cylindrical shells are modelled using a doubled-walled cylindrical shell structure closed at each end by circular end plates and excited by a transverse force at one end. The effects of various influencing factors on the radiated sound power are examined corresponding to non-concentricity of the cylindrical shells, entrained fluid and rib connections in the annular ...
