摘要：

A cylindrical composite shell with a non-circular, symmetric cross-section of flat sides and circular arc corners is analyzed using the ABAQUS finite element program. A trade study on the effects of various corner radii and shell lengths is performed. The response of the shell to constant internal pressurization is studied, with particular attention given to the bending boundary layer (BBL) near the ends. It is found that the extent of the BBL in the non-circular case is 2.5-4 times longer than that predicted by the classical equation, however, the 'intensity' of the bending boundary layer is reduced. An unusual 'compounding' effect in boundary layer response for short non-circular shells is described. (C) 2003 Elsevier Ltd. All rights reserved.
