ABSTRACT
Analysis of discontinuity stresses is not covered in codes; instead compensation methods and mandatory rules to reduce discontinuity stresses are provided. Discontinuity stresses at junctions between the cylinder and sphere and cone and flat are described in this chapter along with a step-by-step general procedure and derivation of equations. An example is given for a cylindrical shell to a hemispherical head for clarity of the procedure. Using this procedure, some of the other discontinuities can be attempted to derive, but they are complicated. Other discontinuities normally found in pressure vessels such as attachments and openings are covered in Chapter 8, and elliptical and torispherical are briefly explained in this chapter.
