Abstract

An adaptive mesh generation scheme is developed for effective non-linear analysis of the shell structures under large deformation. In particular, based on a posteriori error estimation, remeshing method on each load step is of primary interest here. An advancing front method, called paving method, is adopted for remeshing. It can be known that the adaptive mesh generation using contours of spacing values obtained from stress errors has an advantage in the adaptive analysis of the shell structures.

본 연구에서는 대변형 쉘 구조물에 효과적인 적응적 유한요소 자동생성 기법을 제안한다. 사후 오차평가에 기초하여 기하학적 비선형 해석시 각 하중 단계에서의 요소 재생성에 초점을 맞추고 있다. 응력오차로부터 얻어진 요소크기 함수로 등고선을 구성하고, 요소 재생성 기법으로 advancing front method의 일종인 패이빙법(paving method)을 이용하여 적응적 요소 자동생성을 수행한 결과, 그 유용성을 확인하였다.
