Title: Numerical and Experimental Study of Imperfections in the Yarn and its Bond to Cementitious Matrix
Author(s): R. Chudoba, M. Konrad, M. Vorechovsky, and A. Roye

Abstract:This paper describes two models used in the modeling strategy for textile reinforced concrete. The modeling of multi-filament yarns and of the bond between yarn and matrix is focused on micromechanical aspects of the material behavior. The calibration procedure of the model is explained on an example of a detailed experimental and numerical study of pull-out specimen. We demonstrate the use of the model for numerical homogenization to derive effective parameters at the meso level. In parametric studies we analyze the influence of local imperfections in the microstructure arising in the production process on the meso- and macromechanical properties of the material.
