Fracture mechanics of fiber reinforced concrete: Experimental study of composition, geometry and hybridization of fibers

Using of polymeric fibers for reinforced concrete structures has significantly developed in recent years. Polymeric fibers start their contribution in the behavior of concrete members after cracking. In order to a careful investigation into post-cracking behavior need to apply fracture mechanic conc...
