Abstract: Pressure vessels are commonly used for large industrial and commercial applications such as storage, filtration and softening purposes. Pressure vessels usually bear pressure and thermal loadings namely thermo-mechanical loadings and experiences expansion loads due to change in temperature. In this study, design and analysis are performed using commercial code to compare the stresses between different geometries. Structural design of pressure vessel is also optimized to accommodate thermal as well structural loads. Von-mises stress, hoop stress and deformation are plotted for all case studies.
Keywords: Stress distribution, Stress concentration, Geometric non-linearity, Pressure vessels.
