Medial Surface Generation by Using Chordal Axis Transform in Shell Structures
쉘 구조물에서 Chordal Axis Transform 을 이용한 중립면 생성
Abstract
This paper describes the generation of chordal surface for various shell structures, such as automobile bodies, plastic injection mold components and shell metal parts. After one-layered tetrahedral mesh is generated by an advancing front algorithm, the chordal surface is generated by cutting a tetrahedral element. It is generated one or two elements at a tetrahedral element and the chordal surface is composed with triangular or quadrilateral elements. This algorithm has been tested on several models with rib structure.
