121054 - Design and Analysis of Pressure Vessel Using Abaqus Cae and Ansys 

The static structural study of a pressure vessel using ANSYS is presented in this paper. The vessel has an interior pressure of 20 MPa and is composed of structural steel. Standard earth gravity and an upward-facing positive Y direction characterize the boundary conditions. Calculations are made for the equivalent stress analysis and overall deformation. Additionally, the locations and magnitudes of the maximum and minimum stresses are established. A shell element serves as the model for the pressure vessel. The mesh is fine-tuned where it is anticipated that there will be a lot of stress. The elements are given the structural steel's material characteristics. The model is then subjected to the boundary conditions.

It is done to analyze static structures. According to the findings, the circumferential weld joint has the highest equivalent stress. The middle of the vessel experiences the least equivalent stress. The overall distortion is minimal and within allowable bounds.

Using Abaqus CAE, the pressure vessel analysis is also carried out. The two analyses' findings mostly match. This demonstrates the accuracy of the ANSYS model and its suitability for pressure vessel design.

The outcomes of this study can be used to enhance pressure vessel design. The results can also be utilized to improve pressure vessel manufacturing procedures and material selection.

Some of the study's major findings, in addition to the already mentioned, are as follows:

• The circumferential weld joint experiences the highest equivalent stress since it is the location of greatest stress concentration.

The vessel's core, where the stress is the lowest, experiences the least equivalent stress, and the total deformation is minimal and within acceptable bounds. This indicates that using the pressure vessel is safe. The two analyses' findings (ANSYS and Abaqus) accord fairly well. This demonstrates the accuracy of the ANSYS model and its suitability for pressure vessel design.

The results of this study can be used to enhance pressure vessel design. The results can also be utilized to improve pressure vessel manufacturing procedures and material selection.
