Stresses and deformations in egg-shaped sludge digestors: discontinuity effects

摘要

In the first part of this study[J.Eng. Struct. 23(2001)1365-1372], detailed results for stresses and deformation throughout a hydrostatically-loaded egg-shaped sludge digestor were developed on the basis of the membrane hypothesis for shells. However, and as is well-known, such results are generally unreliable around the junctions of the shell components making up the digestor. A significant amount of bending and shearing will occur in the vicinity of these junctions.
