벨로우즈 문제 해석을 위한 수정 에너지 이론

A study on the modified energy theory for the bellows problem

In this paper, the bellows problem under axial load were investigated. A modified energy theory, which has the improved strain energy and stress description taken from governing equation of general shells of revolution, were proposed. From the analysis, the results obtained from the modified theory were more accurate and in stable state with varing geometric parameter of bellows than those of other theory.
