...Eduardo F. P. Silva; Theodoro A. Netto The objective of this paper is to evaluate the design collapse equations presented in Chap. 8 and Annex F of the current standard ISO TR 10400 for casings under external pressure and axial tension. A nonlinear numerical model has been developed to analyze...

...Yongmei Zhu; Bo Zhao; Binbin Chen; Xilu Zhao; Wenxian Tang; Xiaorong Wang The buckling characteristics of toroidal shells with closed circular cross sections loaded with a static external pressure were investigated. Eight toroidal shell test models were developed: two ribless, two semicircular...

... energy due to a uniform external pressure are formulated. Variations of the in-surface and normal displacement components in the circumferential and meridional directions are assumed in the form of a double Fourier series. The eigenvalue problem for the determination of the critical pressure...

... data were obtained for: (i) two cones subjected to axial compression, (ii) two cones subjected to external pressure, and (iii) the remaining two models subjected to combined action of external pressure and axial compression. Apart from axisymmetric modeling of tested cones, true geometry with true wall...

... and stacking sequence. The results confirm that there exists a circumferential stress along with an associate shear stress when the shell is subjected to lateral pressure. The postbuckling equilibrium path is stable for the moderately long shell under external pressure and the shell structure is virtually...

...Lelio Luzzi; Valentino Di Marcello Some innovative nuclear power plant proposals consider for the design tubes of considerable thickness subjected to external pressure (e.g., steam generators tubes). The collapse of thick tubes is expected to be dominated by yielding but, because of the decreasing...

... shell theory postbuckling external pressure The use of composite materials in the marine and offshore industries has been gaining around due to their light weight and high resistance to salt water corrosion. In these applications, they are subjected to a number of load systems, including...

... was subjected to external water pressure up to collapse. The purpose of the test was to confirm the external pressure capacity of the specimen and to provide a basis for verification and calibration of analytical estimates of the collapse pressure of large scale carbon fiber tubes. The specimen was instrumented...
