Hi Everyone,
For rubber expansion joints, note that compression stiffness and elongation stiffness are not the same. So you should use the proper axial stiffness acording to compression or expansion loads. If you search the web, you'll find many rubber bellow suppliers' catalogues. Find a similar material to your exp. jt. and use it. Also note that stiffness values tolerance are +/- 20% in some manufacturers catalogues.
