Numerical Simulation of Cutting Steel Plates by Shaped Charge in Blasting Demolition of Steel Construction
Shaped charge is an effective method to cut steel plates in blasting demolition of steel construction. In order to control the demolition of steel buildings safety and surely, it is accessary that the impact fracture mechanisms of steel plates with shaped charges shall be understood. Therefore, die shaped charge jet and its interaction with steel plates are simulated by using fluid-structure coupling algorithm and die Arbitrary Lagrangian-Eulerian (ALE) method of LSDYNA. Simulation results are compared with the test data, the agreement is reasonably good. The simulation shows die importance of standoff distance.
