Multi-material ALE method combines the advantages of Lagrangian and Eulerian methods, avoids mesh distortion of the Lagrangian method, and eliminates moving boundary problems of the Euler method. A numerical simulation of blast-induced craters in geotechnical medium was performed within the frame of LS-DYNA by multi-material ALE method. The simulated crater which coincides with the empirical data from CONWEP was observed in post processing by the flow of material. This demonstrates that the multi-material ALE method is an effective way to simulate blast-induced craters in geotechnical medium.
