A comparison of numerical methods for computing the exact closure for short-fiber composites

We present efficient algorithms for computing fourth-order fiber orientation tensors associated to the exact closure. Based on quadrature using spherical designs, we investigate Newton’s method as well as a fixed point scheme. These methods serve as alternatives to the original approach utilizing elliptic integrals. We compare the convergence behavior and the computational performance of both algorithms.
