title = "Acoustic emission of steel-fiber concrete under four-point bending",
abstract = "This work deals with the AE behavior of concrete under four-point bending. Different contents of steel fibers were included to investigate their influence on the load-bearing capacity and on the fracture mechanisms. The AE waveform characteristics revealed that, although tension was the dominant mechanism of fracture for the plain material, the increase in the fiber content resulted in extension of the shear failure due to improvement of the weak tensile properties of concrete. Appropriate AE indices employed for early warning prior to macroscopic failure can lead to more suitable design of the reinforcement, in order to withstand the specific stresses.",
