The outline of a Link between Shell Analysis and Surface Modeling for Surface Structural Integrated Design

곡면 구조물 통합 설계를 위한 쉘 해석과 곡면 모델링의 연동 개요

In the present study, we propose the framework which directly links shell finite element to the surface geometric modeling. For the development of a robust shell element, partial mixed variational functional is provided. The NURBS is used to generate the general free form of parameterized shell surfaces. Employment of NURBS makes shell finite element handle the arbitrary geometry of the smooth shell surfaces. The proposed shell finite element model linked with NURBS surface representation provides efficiency for design and analysis and can be directly extended to surface shape optimization problems in future work.
