In the present paper, the fracture behaviour ofHFRC (hybrid fibre reinforced concrete)specimens is examined, with copper andpolypropylene fibrillated fibres being randomlydistributed in concrete. The modified twoparametermodel is employed to compute thecritical stress intensity factor (fracturetoughness), taking into account the possiblekinked crack occurring during the stable crackpropagation.

Abstract
In the present paper, the fracture behaviour ofHFRC (hybrid fibre reinforced concrete)specimens is examined, with copper andpolypropylene fibrillated fibres being randomlydistributed in concrete. The modified twoparametermodel is employed to compute thecritical stress intensity factor (fracturetoughness), taking into account the possiblekinked crack occurring during the stable crackpropagation.File in questo prodotto:
