I am performing an static analysis for a closed rectangular gas tank (steel) with 3mm thickness which is exposed to internal gas pressure of 0.08 Mpa.
Gas tank dimensions are 1400 x 950 x 625 (L x H x W). I need to find maximum deformation and stress values.
Please let me know how to perform hand calculations for the above case for validation purpose.
Note: For FEA simplification,I have took symmetry of gas tank through it length and used midsurface (shell elements) in ANSYS.
Thanks,
Naveen
