Usually fibers are homogeneously distributed in concrete
body having arbitrary spatial orientations [1, 2]. Macro crack
propagation in mechanically loaded steel fiber reinforced
concrete is characterized by fibers bridging the crack,
providing resistance to its opening. Suppose about
homogeneous distribution of spatially arbitrary oriented fibers
in a volume is leading to homogeneous spatially arbitrary
distributed fibers orientation on the surface of the crack. At the
same time is obvious, when macro crack is cutting bended
beam orthogonal crossection, fibers located close to a neutral
axis are loaded very weak or not loaded at all (stretching stress
is equal to zero on the neutral axis and is maximal on the outer
surface of the beam).
