3차원 외팔보의 안정 해석 = Safety Analysis of 3-dimensional Cantilever Beam

국문 초록 (Abstract)

본 연구는 자유단에서 연직하중을 받고 있는 외팔보의 안정 해석을 3차원 경계요소법으로 수행하였다. 경계요소법은 연속적인 지배방정식이 경계적분 방정식으로 변환되어 수행된다. 요소가 면으로 정의되는 경계요소법의 경계적분방정식의 이론이 상세히 전개되었다. 수치해석을 위하여 컴퓨터 프로그램이 개발되었다. 켈빈의 기초해가 프로그램에 이용되었다. 3차원 외팔보의 수치해석에 면 요소(constant quadrilateral element)를 적용시켜 타당성을 입증하고 유한요소법의 결과치와 비교 검토하였다.

다국어 초록 (Multilingual Abstract)

In this paper we carried out a Cantilever beam which is subjected to vertical loads at the end by the three dimensional boundary element method. In the boundary element method, the domain equations are converted into boundary integral equations. A detailed description of the theory of the integral equations in the boundary element method approach, which only requires a surface discretization as a plane element is presented. A computer program is developed for this purpose. The fundamental solution due to Kelvin is employed in this program. A constant quadrilateral element is tested for three dimensional elastostatic Cantilever beam problem and results are presented and the results are compared to the solution of finite element.
