Abstract

This review paper concerns some aspects of computer use in pressure vessel design, including synthesis of analytical and numerical methods, determination of stress intensity factors for cracks in complex stressed areas, and thermal stresses in heat exchanger tubesheets. The author holds that the integration of stress analysis, materials science, and manufacturing procedures is indispensable, and that the designer/stress analyst must be competent in advanced methods of stress analysis, with a solid grasp of structural mechanics, numerical analysis, and digital computer programing, and that from these disciplines he must build solid and preferably 2-way bridges to the metallurgist and the welding engineer.
