(77a) A Bonded Sphero-Cylinder Model for Computational Simulation of Large Aspect Ratio, Flexible Fibers
To illustrate its capability, the developed model is applied to computationally investigate the compressibility of assemblies of fibrous particles. The compression of fibrous materials is frequently encountered in industrial operations, such as briquetting of agricultural materials and processing of wool, cotton and textiles. A better understanding of fiber compression can greatly improve the design of these operating procedures. From the fiber compression simulations, the macroscopic compression properties of bulk material (e.g., bulk compression stiffness) can be measured. The effects of initial particle bed configuration and fiber properties (e.g., aspect ratio, bending stiffness, and friction coefficient) will be explored.
