This paper presents a preliminary finite element study on the effects of strain rate on the FRP-to-concrete bond behaviour using the K&C concrete damage model in LS-DYNA Explicit. The developed FE model uses the first-order eight-node hexahedron 3D solid element with one integration point and a sub-millimetre mesh. Results show that the model can simulate the static FRP-to-concrete bond behaviour with good accuracy and mesh objectivity. It also shows that the loading rate has significant effects on the bond behaviour.
