Hopkinson bar techniques have been used for the investigation of the tensile dynamic behaviour of anchors in normal and fiber reinforced concrete. Anchors with chemical adhesive, undercut, and headed studs have been tested, and concrete cone breakout failure has been predominantly induced. Companion static and dynamic testing of the base materials has also been conducted. Test results show that load–displacement diagrams for dynamic loading tend in general to lie above the corresponding static ones, and that post–installed anchors can achieve comparable load bearing capacity to those cast–in–place. With increasing strength of the base material, failure of the metallic element is often observed.
