The length of the straight section① is Lc ,the curvature radius of ② and ④is R, the corner is β, the length of straight section ③ is L, the total length of the fiber is Lf, the specific values is showed ​​in Tab.1.
Table.1 The specific size of the selected hooked-end steel fibers parameters r Lc R L Β Lf values 0.45mm 1.83mm 2.23mm 1.36mm 0.66 60mm The elastic modulus of the steel fiber is 2.0 × 105MPa, Poisson's ratio is 0.3, tensile strength, 1450MPa,steel fiber is considered ideal plastic.
In order to meet the requirements of the model , the sharp of the section should be changed to the rectangular by equivalent change in area and moment of inertia of area, the length and width of a rectangular cross section to meet the requirements can be obtained by following two equations : ( 1 ) ( 2 ) Fig.1 The shape and size of hooked-end steel fibers Fig. 2 Mesh for the pull-out model of hooked-end steel fiber The ratio of the rectangular cross-section can be calculated by Formula(1) and (2).
Table.2 Two peak loads and the corresponding pull-out displacement load diaplacement The first peak load 479.9N 1.440mm The secondpeak load 314.9N 4.628mm It is showed by Fig.3 that the pull-out process of hooked- end fiber can be divided into the following phases: (1) before the end of the fiber is pulled , the relationship of load and displacement is linear , with the increase of load, the end of the fiber is pulled out, the nonlinear relationship between load and displacement occur, the first peak load appear when the pull-out displacement δ= 0.144mm, yet the end of the fiber of hook is near but do not pass the first corner, (2) after the peak , the end of the fiber begin to pass the first corner and the load began to decline, (3) When the displacement δ= 3.816mm, end of fiber entirely pass the first turn into the straight section ③ and the load began to rise with increase of displacement ,(4) When the displacement δ= 4.628mm, the end of fiber has not yet reached the second
