000008864 520__ $$2eng$$aThe behavior of a single crack in a fiber composite strongly influences its macroscopic tensile behavior after initiation of the cracking. It affects whether the damage locates in one macro-crack or is represented by large amount of fine cracks and the composite retains the ability to carry the tensile stress in hardening response. As part of the research of fiber-reinforced lime-based mortar, the model of a single fiber-bridged crack response was developed, which allows prediction of the cohesive response for experimentally identified micromechanical parameters of individual components of the composite. Subsequently, the direct tensile test was performed with notched specimens of fiber-reinforced mortar to evaluate cohesive relation and also to verify the model. The notch ensures formation and further development of just one crack. The experiment was carried out for several different amounts of fibers in the composite. The results show that the maximum bridging stress is not only affected by strength of the fiber reinforcement, but also by shear strength of the matrix, which reduces the load carrying capacity.
