글라스 세라믹 구형 돔의 충격파괴 모델링 기법 연구
A Study on the Impact Fracture Modeling Techniques of Glass-Ceramic Spherical Dome
초록
This paper studied on the impact fracture modeling techniques of spherical dome with MACOR glass-ceramic. The glass ceramic material has bigger compressive strength than the tensile strength and endure well at high temperature. The fracture simulation under shock perssure was performed by the finite element method with nonlinear code LS-Dyna. The simulation was carried out by 3 type dome models under step impact pulse shape. 4-node shell element and 8-node solid element were used for analysis.
