Abstract
In this study, a 2D multimaterial Eulerian numerical method and an MMIC-2D hydrocode are presented to analyze the explosion and impact effects. The operator of the governing equations is spitted into the Lagrangian and Eulerian parts, so that the multimaterial Eulerian method can be applied. A modified Young's interface reconstruction algorithm is used to treat the material interface in mixed Eulerian cells. The effects of blast in concrete are studied numerically. The numerical results are in good agreement with the experimental data, indicating that the proposed model and algorithm are effective and can be used for engineering design.
