Abstract

This study was presented how to interpret a laminated cylindrical shell having both ends supported condition are simple, and by identifying the three-dimensional stress characteristics. The governing equations were using the concept of finite element assuming the conversion into ordinary differential equations and partial differential equations by numerical analysis using the finite strip method. In particular, a function performed for the three-dimensional laminated cylindrical shell having a simple support condition were analyzed for the case composed of a specific function of the beam consisting of a trigonometric function. Layer material and layer thickness of a steel or concrete, the cylindrical length and the like by varying the parameters variously examine the effects of multi-layer cylindrical shell.

본 연구는 양단이 단순지지된 조건을 갖는 다층 원통쉘을 해석하는 방법을 제시하였고, 3차원 응력 특성을 규명한 것이다. 지배방정식은 편미분방정식을 상미분방정식으로 변환을 가정한 유한요소 개념을 이용하여 유한대판법 해석법을 이용하여 수치해서하였다. 특히 단순지지 조건을 갖는 3차원 다층원통쉘에 대해서는 시행함수로서 삼각함수로 구성되는 보의 고유함수로 구성되는 경우에 대해 해석하였다. 층 재료는 강재 또는 콘크리트로하고 층두께, 원통길이 등 파라메터를 다양하게 변화시켜 다층원통쉘에 미치는 영향을 검토한다.
