ANALYSIS OF PRESSURE VESSEL

Mechanical Engineering

Pressure vessel cylinders find wide applications in thermal and nuclear power plants, process and chemical industries, in space and ocean depths, and fluid supply systems in industries. The failure of pressure vessel may result in loss of life, health hazards and damage of property. In addition to the pressure, the pressure vessels area also subjected to support loads that may be steady or variable, piping reactions, and thermal shocks which require an overall knowledge of the stresses imposed by these conditions on various vessel shapes and appropriate design means to ensure safe and long life. . In this paper, emphasis is on effect of stress concentration. It will be shown that an appropriate location and size of the opening in a pressure vessel results in minimizing the stresses induced due to the stress concentration resulting from the end flanges and other attachments. Also design and optimize the spherical and elliptical head profile with hole on the head, also Analysis the above profiles for various stress parameter.
