A quick-release door closure design (Bandlock 2) is described. The paper presents a case study of the design and analysis of an existing closure geometry. Four techniques for stress analysis of the closure are described: two numerical (finite element and boundary element) an experimental (electrical resistance strain gauge) and an approximate (strength of materials) approach to the calculation of stresses. The stress results are presented in an unnormalized form for an ANSI class 600 test pressure.

Stress categorization is an essential procedure in Design by Analysis (DBA) pressure vessel design methods based on elastic analysis in ASME and EN code. It was difficult to implement especially around structural discontinuities. A new elastic analysis, DBA-L, was proposed recently to avoid stress categorization. A model of the cylindrical pressure vessel with spherical end is used to check the validity of this method by comparing with other design methods based on stress categorization procedures and elastic-plastic stress analysis from ASME and EN code. The results indicate that the DBA-L is an economic and explicit method, and can be used an alternative method to stress categorization.

Saddles are used to support the horizontal pressure vessels such as boiler drums or tanks. Since saddle is an integral part of the vessel, it should be designed in such a way that it can withstand the pressure vessel load while carrying liquid along with the operating weight. This paper presents the stress analysis of saddle support of a horizontal pressure vessel. A model of horizontal pressure vessel and saddle is created in Ansys software. For the given boundry and loading conditions, stresses induced in the saddle support are analyzed using Ansys software. After analysis it is found that maximum localized stress arises at the saddle to vessel interface near the saddle horn area. The results obtained shows that the saddle support design is safe for the given loading conditions and provides the theoretical basis for furthur optimisation.

To save material, the safety factor of pressure vessel design standards is gradually decreased from 5.0 to 2.4 in ASME Boiler and Pressure Vessel Codes. So the design methods of pressure vessel should be more rationalized. Considering effects of material strain hardening and non-linear structural deformation, the elastic-plastic stress analysis is the most suitable for pressure vessels design at present. This paper is based on elastic-plastic theory and considers material strain hardening and structural deformation effects. Elastic-plastic stress analyses of pressure vessels are summarized. Firstly, expressions of load and structural deformation relationship were introduced for thin-walled cylindrical and spherical vessels under internal pressure. Secondly, the plastic instability for thin-walled cylindrical and spherical vessels under internal pressure were analysed. Thirdly, to prevent pressure vessels from local failure, the ductile fracture strain of materials was discussed.
