This paper applies an Eulerian hydrocode to fracture analyses of solid material. The hydrocode treats the solid like fluid and includes not only momentum but also mass and energy equations for conservation. The Eulerian description fixes meshes on space and materials flow through the fixed meshes. Hence, the Eulerian code allows arbitrarily large deformations and new free surfaces without a special algorithm. Fracture phenomena, which are difficult to compute by conventional structural codes in the Lagrangian description, can be simulated by the Eulerian hydrocode.
