Fracture energy of concrete at high loading rates in tension

The effect of high loading rates in tension on the failure energy and strength of concrete is reported in this paper. High loading rates exceeding 5000 GPa/s corresponding to strain rates higher than ∼120 s −1 can be applied by use of Hopkinson bar set-up designed to produce spall. Tension tests wer...
