The use of finite element inelastic analysis to partition mechanically induced stresses into the Primary and Secondary categories was introduced in Reference. The simple two-dimensional case of the plate-to-shell joint was used to illustrate the evaluation technique. Application of the proposed method for the nozzle-to-shell connection subjected to external loads and pressure is discussed. The analyzed model also includes body forces due to high static shock accelerations. The results of elastic analyses are compared with those obtained by more effective inelastic analyses. The use of inelastic analyses shows that efficient designs are acceptable even where elastic stresses are about twice the allowable values.
