摘要
本文采用经典的显式有限元动力程序LS—DYNA,模拟商用大型飞机对AP1000核岛屏蔽厂房的撞击。混凝土有限元动力模型采用Holmquist—Johnson—Cook45型,模拟混凝土在大应变、高应变率和强挤压下的非线性性能,同时评估屏蔽厂房的抗飞机撞击能力。
To simulate the kinetic response of AP1000 Shield Building concrete walls subjected to large strain, high strain rate and high pressure when large commercial aircraft impacting, the explicit finite element method is used in the anslysis.The concrete constitutive relations and damage model is simulated by HJC (Holmquist-Johnson-Cook) model.So we could evaluate the anti-impact capacity of the Shield Building wall for the large commmercial aircraft.
