Stochastické modelování mnohovláknitých svazků pro vyztužení betonu

Original language description

The paper presents numerical studies of sources of randomness as they occur in laboratory tensile tests of multifilament yarns of glass textile reinforcement for concrete. The main phenomenon under study is the length effect on the yarn tensile strength.The newly formulate deterministic micromechanical model constitutes the stepping stone for stochastic simulations of strength and the whole response to tensile load. We study sources of randomness both across the yarn and along the filaments. Emphasizeis given to simulation of spatial variability by random fields and the existence of statistical length scales. The analyses are compared to theoretical and laboratory results and the directions of future research are recommended.
