An experimental and finite element analysis of the impact of a stel rod on a reinforced concrete slabl has been conduted. The object was to study the correlation between experimental and theoretical results. It was found that detailed information of nonlinear wave propagationm concrete crushing and cracking, and yielding of reinforcment steel could be obtained from the finite elem,ent analysis. A good coorelation between experimental and theoretical results was achieved. The development of different failure mechanisms can clearly be followed in the theoretical results. Such information should be very valuable in connection with the formulation of simple design formulas.
