    Abstract
  • According to the previous simulation results of two-dimensional fluid-structure interaction, the model of impulsive load generated by a single explosive rod and shaped by the buffer is built. Then the loads generated by multiple explosive rods are superposed and applied on the surface of the cylindrical shell, and a two-dimensional decoupled simulation is performed. The results basically agree with those of the fluid-structure interaction simulation. Based on that, a three-dimensional decoupled simulation of the 265 mm380 mm cylindrical shell loaded by 19 explosive rods is accomplished. Meanwhile, the corresponding test is performed. There shows a good agreement between the three-dimensional numerical and tested strain histories at typical locations. These results prove the effectiveness of decoupled numerical simulation and provide a foundation for improving the modeling and computational efficiency in performing a large number of numerical simulations.
