Abstract
The mechanical response of a bellows under impact loading and unloading was determined by the strain-gauge method and analyzed by the finite element method (FEM). It was found that the FEM simulated strain responses agree well with the experimentally measured ones, and the maximum axial stress occurs on the inner surface of the inner corrugation nearest the fixed end of the bellows. Amplitudes of the stress response increase with increasing loading or unloading speeds on the bellows.
