I did a Calculation of 13-10 UNREINFORCED VESSELS HAVING AN OBROUND CROSS SECTION.
The value of stress I obtained was high. I checked all the calculations and have doubts about two things:
[ol 1]
The value of Moment of Inertia, which is bt^3/12.
Neutral axis to Extreme distance (c). I used this...
I did support lug FEA as per ASME Section VIII Div-2, Part 5, Elastic Stress Analysis Method (5.2.2). The model in analysis consists of Support Lug Assembly, Heads, Shell and fillet weld between Support Lug and Shell. The material properties of Shell and Support Lugs are as follows:
Allowable...
Issue: The stress on F&D head is extremely high in ANSYS Workbench as compared to ASME VIII Div-1 calculation.
Vessel OD: 96”, 106” Seam-Seam
Thickness: 0.4375”
Pressure: 105 psi
Material: SA-24 316L.
The baseplate of Leg as fixed.
I did ANSYS analysis for F&D (ASME 80:10) head. The obtained...
