[MW:29441] [Urgent] Tube to Tubesheet Calculation

Hi,

I am new to this topic. I have to solve the engineering part of doing the calculation.

Here is the statement of problem-->

Take the actual nominate tube and tube sheet material, conduct analysis
mathematically to estimate the joint strength.
 Conduct analysis to estimate the maximum expansion the tube can take
without affecting the integrity of the tube section. (Check the wall thickness
reduction in %)
 Once the maximum expansion on tube has been calculated, check the tube
to tube-sheet joint:
 0.25mm oversized hole with the tube at maximum expansion
 0.5mm oversized hole with the tube at maximum expansion
 0.75mm oversized hole with the tube at maximum expansion

Nominal tube diameter-38.1 mm
> Nominal tube sheet hole-38.56 mm 

tube thickness 3.2 mm

Tube material SS 304

TEMA Extract (values in mm, bracket in inches

38.10 (11/2)  Tube nominal dia

38.56 tube sheet nominal dia
(1.518)
0.18 under tolerance 
0.08 over tolerance 
(0.003)

I have calculated maximum expansion of the tube as per the attached excel. Can someone help me to make the calculation for the above statement?

Thanks
