Neural network meta‐model of fibrous materials based on discrete‐event simulation. Part 1: discrete‐event simulation model of one‐dimensional fibrous material

We present a new approach to the simulation of one‐dimensional fibrous material irregularity. This approach is based on the idea of a random simulation step and the ability to trace each separate fiber or group of fibers during computer simulation. The simulation models developed are free of restrictions inherent in theoretical models and can simulate irregularity in a wide range of statistical distributions and simulation conditions. This paper presents the basic model of fibrous materials made from homogeneous separated fibers and its extension to blended fibrous materials, a model of thickness irregularity, and the extension of the basic model to a random group of fibers. The effects of the fiber length and fiber front ends were also simulated and analyzed.
