Abstract

Aiming at the problem of non-contact explosion of mines and other shallow buried improvised explosive devices on protective structures, the *INITIAL_IMPULSE_MINE(IIM) algorithm based on the empirical model was used to numerically simulate the soil burial test rig and comparatively analyze the dynamic response of the target plate under the two algorithms of ALE and S-ALE. The simulation results show that, in terms of computational speed, the IIM algorithm, due to the absence of a flow field grid and the need for fluid-solid coupling processing, greatly increases the computational speed, which is only 6% and 8.7% of that of the ALE and S-ALE algorithms; however, in terms of computational accuracy, the IIM algorithm has the largest error relative to the other two algorithms, which reaches 20.3%.
