Optimal Design of Filament Wound Structures under Internal Pressure based on the Semi-geodesic Path Algorithm

준측지궤적 알고리즘을 적용한 내압을 받는 필라멘트 와인딩 된 복합재 축대칭 구조물의 최적설계

This research aims to establish an optimal design method of filament wound structures. So far, most design and manufacturing of filament wound structures have been based on manufacturing experiences, and there is no established design rule. In this research, possible winding patterns considering the windability and the slippage between fiber and mandrel surface were calculated using the semi-geodesic path algorithm. In addition, finite element analyses using a commercial code, ABAQUS, were performed to predict the behavior of filament wound structures. On the basis of the semi-geodesic path algorithm and the finite element analysis method, filament wound structures were designed using the genetic algorithm.
