This study aims to clarify experimentally the uniaxial tension-compression fatigue behavior and fiber bridging stress degradation of strain hardening fiber reinforced cementitious composites. During fatigue cyclic loading, tensile bridging stress corresponding to the preset maximum tensile strain was recorded with the number of cycles in order to observe the degradation of the tensile bridging stress. Major bridging stress degradation was observed before reaching 1,000 cycles, and microscopic observation of the failure surface confirmed severe fiber damages. Fitting curves of bridging stress degradation are 2 proposed with the idea of Weibull distribution. The preliminary results of the current study with a limited number of specimens are compared with those of a uniaxial tensile fatigue study, and the differences of bridging stress degradations are discussed.

“…For the sake of comparison, the predictions of the present model in terms of unstable fracture bending moment are reported in Table 1 together with those of the theoretical model by Matsumoto and Li (1999), for different values of the crack depth. Note that the reported results of Matsumoto and Li refer to the net contribution of fibers to crack bridging, i.e.…”

“…Some theoretical models have been proposed to describe such phenomena and predict fatigue life (e.g. for metal-matrix composites with continuous fibers, see the models reported in Bao andBegley and for cementitious composites with short fibers, see the recent models presented in Zhang and Stang, 1998, Zhang et al, 1999, and Matsumoto and Li, 1999. In the present paper, a cracked portion of a straight beam subjected to an external cyclic bending moment and the crack bridging actions due to the fibers is analysed (Fig.…”

A fibrous composite beam with an edge crack is submitted to a cyclic bending moment and the crack bridging actions due to the fibers. Assuming a general elastic-linearly hardening crack bridging model for the fibers and a linear-elastic law for the matrix, the statically indeterminate bridging actions are obtained from compatibility conditions. The elastic and plastic shake-down phenomena are examined in terms of generalised cross-sectional quantities and, by employing a fatigue crack growth law, the mechanical behaviour up to failure is captured. Within the framework of the proposed fracture mechanics-based model, the cyclic crack bridging due to debonding at fiber-matrix interface of short fibers is analysed in depth. By means of some simplifying assumptions, such a phenomenon can be described by a linear isotropic tensile softening/compressive hardening law. Finally, numerical examples are presented for fibrous composite beams with randomly distributed short fibers.

“…Here, in addition to the law under monotonic loading, the law under cyclic loading is required. These two equations (8) and (9) The first tam for fibers that have been in debonding stage can be obtained with the use of (8). Replacing z/(Lf/2) with z', the integration leads to where z0=1-•@ , ƒ¢ƒÂ=ƒ¢ƒÂ/(Lf/2), and ƒÂmax= ƒÂmax /(Lf/2).…”

This paper presents the micromechanical modeling of fiber bridging constitutive law of a discontinuous fiber reinforced composite (DFRC) under cyclic loading. Fiist, the derivation of fiber bridging constitutive law under monotonic loading is briefly reviewed to highlight the approach to obtain the bridging stress carried by randomly distributed discontinuous fibers. Second, the relation between single fiber pa-out/push-in load amplitude and crack opening displacement amplitude under cyclic loading is derived. Third, fiber bridging constitutive l aw under cyclic loading is derived and obtained in two ways: numerically and analytically. Finally, the fiber bridging constitutive law is compared with experimental data of a cyclically loaded fiber reinforced concrete (FRC), and its validity is shown.
