Originální abstrakt
The paper presents numerical studies of major sources of randomness as they occur in laboratory tensile tests of multi filament yarns of glass textile reinforcement for concrete. The main phe-nomenon under study is the length effect on the yarn tensile strength. The newly formulated de-terministic micromechanical model constitutes the stepping stone for stochastic simulation of strength and the whole response to tensile load. We study sources of randomness both across the yarn and along the filaments. The analyses are compared to theoretical and laboratory results. Emphasis is given to simulation of spatial variability of local strength by random fields and the existence of statistical length scales and modeling of slack induced by filament waviness. As the actual goal of the present work is to derive yarn characteristics relevant for crack bridges in ce-mentitious composites we systematically assess the significance of the studied sources of disorder in the context of extremely short bundle lengths.
