Dear Sir/Madam,

Please somebody help me. I am getting confused , how to calculate the stiffness factor for bellows, i.e. Axial stiffness , Lateral stiffness, Bending stiffness according to different Diameter, temp & pressure.

Hi gyana

You are not suppose to calculate bellow stiffness data.
Vendor to provide the same.
If you ask caesar to model bellow it will pick metallic bellow data available in caesar data base. You have to confirme the data by vendor.

For metalic bellow you can use EJMA (Expansion Joint Manufacturers Association, Inc.) standards.
For rubber bellow you must ask the vendor for all data.

Many many thanks to you.
