Numerical Analysis of Responses of a Elasto-plastic Tube under Kerosene-air Mixture Detonation

케로신-공기 혼합물의 비정상연소 모델과 탄소성 관의 동적 거동 수치해석

This paper presents a numerical investigation on kerosene-air mixture detonation and behaviors of thermal elasto-plstic thin metal tube under detonation loading based on multi-material analysis. The detonation loading is modeled by the kerosene-air mixture detonation which is compared with CJ condition and experimental cell size. And the thermal softening effect on elasto-plstic model of metal tube is indicated by different dynamic response of detonation loaded tube in various temperature and tube thickness.
