The authors have developed a constitutive model of the three dimensional Rigid-Body-Spring Model with random geometry for quantitative evaluation of the softening and localization of concrete subjected to lateral pressure and uniaxial compression. In the present study, numerical simulations of concrete plates subjected to high velocity impact using the proposed model were conducted for validation of the applicability to the evaluation of the local damage subjected to impact loads. By comparing numerical results with the experimental results, we confirmed that the proposed model can reasonably evaluate the local damage of concrete plates. In addition, the crack propagation behavior and the stress transfer mechanism of local damage were discussed.
