Flanged Expansion Joint seal
The load value required to make the metal bellows or other elastic elements produce unit displacement is called the stiffness of the element, which is generally represented by "K". If the elastic properties of the element are nonlinear, the stiffness is no longer constant, but varies with increasing load. For general engineering bellows-like elastic elements, the stiffness tolerance can be limited to within +/-50%. The stiffness of the bellows is divided into axial stiffness, bending stiffness, torsional stiffness, etc. according to the nature of the load and displacement.

The load value required to make the metal bellows or other elastic elements produce unit displacement is called the stiffness of the element, which is generally represented by "K". If the elastic properties of the element are nonlinear, the stiffness is no longer constant, but varies with increasing load. For general engineering bellows-like elastic elements, the stiffness tolerance can be limited to within +/-50%. The stiffness of the bellows is divided into axial stiffness, bending stiffness, torsional stiffness, etc. according to the nature of the load and displacement. In the application of bellows, most of the stress is axial load, and the displacement mode is linear displacement. The following are several main bellows axial stiffness design calculation methods:
1. Energy method to calculate bellows stiffness
2. Empirical formula for calculating bellows stiffness
3. Numerical calculation of bellows stiffness
4. EJMA standard stiffness calculation method
5. TOYO calculation method of stiffness
6. American KELLOGG (new method) calculation method of stiffness
