FINITE ELEMENT ANALYSIS OF ELASTIC STRESSES FOR CYLINDRICAL SHELL CYLINDER-NOZZLE INTERSECTION UNDER COMBINED LOAD

摘要：

Finite element analysis of elastic stress for cylinder-nozzle intersection under internal pressure and in-plane nozzle moment was carried out. The distribution and superposition of elastic stress under combined load were compared with under separate loads. The result indicates that stresses induced by different load do not exist an absolute relation of linear superposition in cylinder-nozzle intersection area. The total stress value under combined load is not completely equal to the total value gotten by mathematically adding the two stress values under separate load. There are differences between the two total values, but the differences are so small, therefore, it will be true to suppose that stresses induced by different load are linearly superposed in cylinder-nozzle intersection area all the same.
