    **Design of Pressure Vessels–3

    Design of Pressure Vessels–3 DESIGN OF THIN WALLED PRESSURE VESSELS There are two types of thin walled pressure vessels. (i) Thin walled welded pressure vessels (ii) Thin walled riveted pressure vessels Design of a pressure vessel consists of two parts. Design of Shell Design of Head(s) or End Closure(s) Design of shell includes (i) Selection […]

    Discontinuity Stresses

    DISCONTINUITY STRESSES A designer should establish the type of discontinuity and then discontinuity stresses in design of pressure vessels /pipes. Two types of discontinuities (i)                 Gross structural discontinuity (ii)                Local  structural discontinuity Gross Structural Discontinuity A discontinuity which increases the stress or strain which affect a relatively large portion of the structure. It significantly affects the overall […]
