爆炸作用下混凝土板破坏数值模拟

Numerical Simulation on Destruction of Concrete Board Medium under Explosion Action

利用有限元计算软件LS-DYNA建立板状结构介质破坏的三维模型,并用LS-DYNA970软件的求解器和后处理器对板状结构介质在爆炸作用下的破坏过程进行了数值模拟。通过数值模拟,再现了炸药爆炸后,冲击波的传播过程以及板状介质的变形过程,分析了爆破动载作用下板状结构介质破坏情况。

A 3-dimensional numerical model of board medium is built with the help of LS-DYNA, and the destruction process of the board medium under explosion action is numerically simulated on the basis of LS-DYNA970 solvers and post-processer. The numerical simulation reproduced the transmission process of the shock wave and the deformation process of the board medium situation after explosion. In this paper, the destruction process of board medium under dynamical explosion action is analyzed.
