Abstract

A model analysis is used to predict the impact response of a simply supported elastic circular cylindrical shell composed of two bonded isotropic layers. The governing equations for a two-layered cylindrical shell are derived on the basis of an improved theory for the single-layer shell which includes the effects of transverse shear deformation and rotary inertia. Calculations are made for the specific case of the steel-concrete cylindrical shell subjected to a suddenly applied load. The solutions show that the method yields very good results. Therefore the proposed method is useful not only for a better investigating of the response characteristics of the shell but also available for a check on other numerical methods such a FEM.

충격하중을 받는 단순지지된 2층 원통쉘의 탄성 충격응답해석에 대한 모델해석을 실시하였다. 2층 원통쉘에 대한 지배방정식은 전단변형과 회전관성을 고려한 단층 수정쉘 이론을 적용하여 충격하중을 받는 철-콘크리트 원통쉘에 대해서 해석하였다. 수치결과에서 알 수 있듯이 응답의 기본적 특성 이해 및 유한요소법 등의 수치해법에 대한 정도 확립에 유효하게 이용될 수 있다고 생각한다.
