Abstract
From the viewpoint of protective design for the construction of concrete structures, this study is to present an estimation method of local damage in concrete plate due to high velocity impact of rigid projectiles. The method of evaluating local damage is a method which compares the calculated maximum impact load and the critical load at occurrence of scabbing. To calculate the penetration depth, a theoretical model is modified by considering both the strain rate and constitutive model. Also, to predict the local damage modes of concrete, the existing punching shear formula is modified. By using this modified model, it can be obtained the agreeable results with test results. Finally, the utility of this estimation method is verified by comparing with the past test results.
