Abstract: A Eulerian code MEPH2Y is combined with a Lagrangian code LTZ-2D to analyze perforation of jet and projectile on a concrete plate. The hybrid code advantages in calculation the formation of jet and projectile. High resolution on penetration and damage of concrete target are obtained. Jet penetration and damage of the concrete target are simulated and compared with experimental results. Jet penetration and damage of concrete target simulated agree well with test data.

Key words: mechanics of explosion, numerical analysis, jet, penetration, concrete, damage
