This study is to find the local damage and failure of concrete plate due to the contact and close-in explosion by C4 explosive. First, to examine the blast effects by C4 explosive, basic explosion tests were done. Then, the relation between the maximum overpressure and distance from an explosive source is formulated. Next, to examine the local damage and failure of concrete plate due to the contact and close-in explosion by C4 explosive, the small scale explosion tests were carried out. In tests, the concrete plates (50cm x 50cm square) were employed. And, to know the material model and parameter to be used for the hydro code AUTODYN, some of test cases were numerically simulated.
