Abstract

The paper presents a numerical approach for incorporating the effect of orientation of fibers in the stress–strain behavior of fiber-reinforced soils. The results from the numerical analysis of stress–strain response of soil with random fiber distribution are validated with experimental results. The results show that the fibers aligned in horizontal direction in the direction of maximum extension are most beneficial. A series of numerical simulations covering different orientations of fibers have been conducted and the results are presented. The results indicate that the assumption of random fiber distribution is conservative.
