Abstract :
For the dynamic-response of concrete under strong impact loading we adopt the method coupling Euler and Lagrange based fluid dynamics. Control equations are solved on discrete meshes; the influence of pressure giving velocity grad and specific internal energy is considered in Lagrangian step; the transportation of matter is calculated in Eulerian step though programming of Fortran (Power station 4.0); numerical results is visualized by independent software Visc3d; three dimension numerical simulation, which aluminum piece impacts the concrete target, is given. We present an improvement method based on the principle of automatic cellar in order to solve rock failure, which is not perfectly describing by macro plastic and elastic continuous model.
