The ability to analyze the behavior of pressure vessels with structural defects has been greatly improved by the general availability of PC based finite element analysis programs. In this study a hemispherical head with a nozzle and a local thin area is analyzed using finite element models. The requirement to apply a 15 % stress adjustment is also examined in light of the results of the finite element analyses.

Keywords:
Local thin areas, hemispherical head, plasticity
