A novel workflow is developed wherein a random configuration of hundreds of finite-length crimped fibers embedded in a soft matrix can be created, meshed, and then simulated by 3D finite element methods. We show that the mechanical behavior of these composites is affected by the degree of fiber crimp, the fiber volume fraction, and fiber orientation. The degree of reinforcement of the soft matrix was found to increase with volume fraction of the fibers, and with better alignment of the fibers along the tension direction. Fibers with larger crimp amplitude were found to show strain hardening behavior, i.e. contribute little to the stress at small strain, but much more at large strain. The Holzapfel-Gasser-Ogden model is shown to capture the stress-strain behavior adequately. Further, we show that simulations of a single fiber embedded in a soft matrix can approximately predict the mechanical behavior of multifiber composites at much reduced computational cost.
