NASA technical memorandum presents parametric study of additional stresses introduced into cylindrical pressure vessel that is round except for radial mismatch in longitudinal butt weld in sidewall. Prompted by concern over fatigue caused by cyclic stresses in longitudinally welded cylindrical titanium inlet of high-pressure turbopump in main engine of Space Shuttle. Results applicable to any round cylindrical pressure vessel characterized by parameters, and conform to simplifying assumptions, used in analysis.
