本文对一起飞机撞毁核电站外安全壳事故进行了分析。在时间推进方案中，通过计算反应时间来同时考虑目标屈服的影响。所采用的混凝土模型能够预测混凝土的开裂和屈服。研究了不同的飞机在不同的开裂应变和不同的撞击位置下的响应。已经调查了飞机打击围堵的关键位置。所采用的分析方法和材料模型能够表示安全壳结构的飞机撞击响应。
In this paper, analysis of an aircraft crash upon an outer containment of a nuclear power plant is presented. The effect of target yielding is considered simultaneously by calculating the reaction time in a time marching scheme. The concrete model employed is capable of predicting the cracking and yielding. The response for different cracking strains and different locations of aircraft strike for different aircraft has been studied. Critical location of aircraft strike for the containment has been investigated. The analytical procedure and the material model used are found to be capable of representing the aircraft impact response of the containment structure.
