In other situations, the load step at which element birth or death should take place is known in advance. Now, the example in this article considers equivalent stress as a criterion for killing elements. Industrial Equipment and Rotating MachineryĬriteria of Equivalent Stress in Mechanical.Torsional Vibration Measurements Testing.Fluid Flow & Thermal Applications (CFD).Electronic and Electrical Applications (EM).It is required, however, that all loadings (the forces applied to a vessel or its structural attachments) must be considered. It is recognized that high localized and secondary bending stresses may exist but are allowed for by use of a higher safety factor and design rules for details. In general, pressure vessels designed in accordance with the ASME Code, Section VIII, Division 1, are designed by rules and do not require a detailed evaluation of all stresses. The theoretical values and ANSYS values are compared for both solid wall and Head of pressure vessels. The stresses developed in Solid wall pressure vessel and Head of pressure vessel is analyzed by using ANSYS, a versatile Finite Element Package. Various parameters of Solid Pressure Vessel are designed and checked according to the principles specified in American Society of Mechanical Engineers (A.S.M.E) Sec VIII Division 1. The main objective of this study is to design and analyze the features of pressure vessels.
Pressure vessels find wide applications in thermal and nuclear power plants, process and chemical industries, in space, ocean depths and fluid supply systems in industries. The literature has indicated a growing interest in the field of stress concentration analysis in the pressure vessels. This study is about some of the current developments in the determination of stress concentration factor in pressure vessels.
