In the present paper, the fracture behaviour of HFRC (hybrid fibre reinforced concrete) specimens is examined, with copper and polypropylene fibrillated fibres being randomly distributed in concrete. The modified twoparameter model is employed to compute the critical stress intensity factor (fracture toughness), taking into account the possible kinked crack occurring during the stable crack propagation.

Abstract
In the present paper, the fracture behaviour of HFRC (hybrid fibre reinforced concrete) specimens is examined, with copper and polypropylene fibrillated fibres being randomly distributed in concrete. The modified twoparameter model is employed to compute the critical stress intensity factor (fracture toughness), taking into account the possible kinked crack occurring during the stable crack propagation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
