The shakedown theory and basic relations to develop an upper bound technique for the analysis of thin axisymmetric shells has been represented in Part 1 of this paper. Here numerical solutions consisting of the shakedown or limit load and the corresponding collapse mechanism are compared with other numerical and analytical solutions for a range of shell geometries. © 1997 John Wiley & Sons, Ltd.
