Originální abstrakt
Micromechanical modeling of multi-filament yarns is an essential issue needed for understanding and predicting their behavior in different structural contexts. Moreover, due to a high amount of imperfections in the yarn structure, statistical treatment of the micromechanical model is inevitable. It must be stressed that the performance is rather sensitive with respect to the loading context and structural modifications. Especially in the crack bridge with extremely short effective length, a severe reduction of the peak load due to imperfections in the yarn structure can be observed. In order to adapt the traditional fiber bundle models for applications in Textile Reinforced Concrete (TRC) refined kinematicsreflecting the deformation of each filament has been formulated. This becomes extremely important in the modeling of short bundles bridging the cracks. This issue is numerically documented on studied effects of scatted filament lengths, delayed activation and twist of yarns.
