Abstract: 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. Basic considerations in the design of pressure vessel include recognition of most likely modes of failure, stresses induced due to temperature and pressure, selection of suitable material capable of withstanding the effects of pressure and thermal loads and effects of environment and effect of concentration of stresses. In the present work, 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. In this present work we also design and optimize the spherical and elliptical head profile with hole on the head, also Analysis the above profiles for various stress parameter.
