The　dynamic　mechanical　properties　of　concrete　and　reinforced　concrete　targets　subjected　to　high-speed　projectile　impact　loading　have　a　significant　influence　on　the　impact　resistance　of　protective　structures.　In　this　study,　high-speed　projectile　penetration　and　perforation　of　concrete　and　reinforced　concrete　structures　was　carried　out　to　determine　the　high-energy　impact　loading.　The　failure　behaviors　of　projectile　penetration　and　perforation　of　the　concrete　and　reinforced　concrete　targets　were　investigated,　and　the　destruction　characteristics　of　the　targets　were　measured.　An　analytical　model　was　established　using　the　principle　of　minimum　potential　energy.　The　results　show　that　the　theoretical　predictions　are　consistent　with　the　experimental　data,　indicating　that　the　energy　method　is　effective　for　predicting　the　dynamic　mechanical　properties　of　concrete　and　reinforced　concrete　targets　under　high-speed　projectile　penetration.
