摘要
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核岛屏蔽厂房的撞击,混凝土有限元动力模型采用Holmquist-Johnson-Cook模型,用来模拟混凝土在大应变、高应变率下的非线性性能,同时评估屏蔽厂房的抗飞机撞击能力。
Explicit kinetic finite element method(LS-DYNA) is adopted to simulate the impact of large commercial aircraft into the NI shield building.The concrete kinetic finite element model adopts HJC(Holmquist-Johnson-Cook) model to stimulate the non-linear behavior of concrete subjected to large strains and high strain rates.So we could evaluate the capacity of the shield building wall to resist aircraft impact.
