摘要 为评估强爆炸的毁伤效应,在已有的辐射流体力学及结构动力学响应部分工作的基础上,本文采用流固耦合方法对耦合界面进行了处理,并考虑辐射输运引起的能量沉积过程,使得强爆炸产生的辐射波、冲击波和结构动力学响应两部分可以较好地耦合计算,从而能够较完整地模拟爆室内强爆炸的辐射流体动力学过程。计算结果与定性物理分析相符,证明了算法的可行性与程序的正确性。 A cylindrically symmetric two-dimensional computer program has been developed in virtue of the consistent treatment of the interface＇s condition between the zone governed by radiation hydrodynamics and that by hydro-elasto-plastic one. It has been used to simultaneously simulate radiation-generated shock wave and dynamic response in detonating room under strong explosion. The reliability of the linking method between the different simulation regions of the fluid and solid phases is validated by some examples, and the numerical results agree qualitatively with the theoretical analysis.
