Abaqus CAE File: Oil Storage Tank Wall Stress Analysis

This Abaqus CAE model investigates the stress distribution in the wall of a thin-walled steel oil storage tank subjected to internal hydrostatic pressure.

The tank is completely filled with oil. The model represents the tank as a three-dimensional thin-walled cylindrical structure and evaluates the stresses produced by the oil pressure acting on the tank wall.

Model Specifications

• Tank height: 4.23 m
• Tank diameter: 22 m
• Wall thickness: 9 mm
• Tank type: Thin-walled cylindrical tank
• Analysis: Static structural analysis
• Model: 3D Abaqus model
• Loading: Hydrostatic pressure from the oil
• Main output: Stress distribution in the tank wall

The hydrostatic pressure varies with the vertical position of the tank wall, increasing toward the bottom of the tank. This model can therefore be used to study how the internal oil pressure affects the structural response and stress distribution of the tank.

What You Can Learn

This CAE file is useful for learning how to:

• Create a 3D thin-walled storage tank in Abaqus.
• Define steel material properties.
• Apply hydrostatic pressure to a tank wall.
• Set appropriate boundary conditions for a cylindrical tank.
• Analyze stress distribution under internal fluid pressure.
• Evaluate deformation and structural response.
• Visualize important Abaqus results such as von Mises stress, principal stress, and displacement.

The model provides a practical example of applying finite element analysis to industrial storage tanks and pressure-loaded thin-walled structures.

Note: The model focuses on the structural response of the tank wall under hydrostatic loading. It does not perform a coupled fluid–structure interaction analysis.
