The reliability of a designed ductile component or structure can be verified by determining the maximum equivalent stress (Von Mises stress). This work evaluates the design calculations profoundly by preparing a three dimensional model in Catia V5 R19 and then performing a finite element analysis (FEA) analyses on the pressure vessel model for determining the maximum equivalent stress. Several sizes of meshes were incorporated in order to achieve the actual value of maximum equivalent stress. The maximum equivalent stress value obtained for FEA analysis was 136.28MPa and the result obtained through calculations was 132.9742025 MPa, a deviation of 2.4860% was noticed. The maximum equivalent stress obtained through calculations were lesser in analogous to yield strength of the material SA 283 C grade (132.9742025 MPa < 245 MPa), therefore it can be concluded that the design of for flat dish end pressure vessel is safe and can be implemented for various applications.

Keywords: Flat dish end pressure vessel, three dimensional model, finite element analysis (FEA) and Von misses stress.
