Numerical Analysis Of The Interactive BehaviorOf Concrete Structures Under Explosive Loading

This study presents numerical simulations of dynamic fractures of two concrete structures subjected to explosive loading using the hydrocode AUTODYN. In the analytical model, the Euler-Lagrange Coupling method.was employed. First, a method to predict the propagation of a blast wave from inside to outside of an arch was proposed. Next, the failure behavior of an actual large tunnel structure with inner steel liner was simulated. Results from the analysis demonstrated that complicated physical systems could be simulated with appropriate computer codes, numerical modeling, and materials.
