PT Unknown AU Mehta, A Schneider, M TI comparison of numerical methods for computing the exact closure for short-fiber composites SE BeyondRVE: Beyond Representative Volume Elements for Random Heterogeneous Materials PD 11 PY 2024 DI 10.1002/pamm.202400202 LA en AB 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. ER
