CONE CYLINDER INTERSECTION UNDER INTERNAL-PRESSURE - NONSYMMETRIC BUCKLING

Large circumferential compressive membrane stresses arise at the inter section of the large end of a cone and a cylinder when subjected to un iform internal pressure. Such intersections may fail by axisymmetric c ollapse involving excessive axisymmetric inward deformations or by non symmetric buckling. This paper presents a detailed finite-element inve stigation into the nonsymmetric bifurcation buckling behavior and stre ngth of these intersections. Buckling pressures of a wide range of she ll geometries are found, leading to the establishment of accurate and simple buckling strength equations. These equations are then used, tog ether with the strength equations for axisymmetric collapse developed in previous work, to define the range of shell geometries whose streng th is governed by nonsymmetric buckling.
