Abstract

Fiber reinforced concrete beams with varying notch depths and different volume fractions of steel fibers were tested. The results were analyzed to examine the applicability of various fracture mechanics approaches including: critical stress intensity factor, J-integral, critical crack opening displacement, compliance technique for determining the slow crack growth and R-curve analysis. Attempts were made to identify a fracture parameter which is independent of test-specimen geometry and which can correctly predict the effects of fiber addition. R-curve method appears to be promising.
