✦ Synopsis

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.

This paper describes the theory and the fundamental relations for the development of a displacement formulation for the finite element shakedown and limit analysis of axi-symmetrical shells. The material is assumed to be elastic-perfectly plastic. The technique is developed based upon an upper bound
