Numerical simulations of impacts using combined finite-discrete element method

One of very interesting problem in civil engineering applications is reinforced concrete structures subjected to impact load which are often used in protective purpose. Frag- mentation that may occur during impact cannot be modelled by the continuum methods. Predicting of the behaviour of reinforced concrete structures under impact imposes the need to develop numerical model which will be able to include effects of the behaviour of concrete structures due to dynamic action in linear elastic stage, crack initiation and propagation, en-ergy dissipation mechanisms due to non linear effects, inertial effects due to motion, contact impact and finally to attain state of the rest that is a consequence of energy dissipation mechanisms in the system. It is possible to include all previously mentioned effects with the finite - discrete element method (FEM/DEM).
