摘要: Abstract Monte Carlo (MC) runs are employed to generate statistically independent realizations of a periodic elastic composite with disordered unit cell made up 8, 27, and 64 nonoverlapping identical spheres. In the limit an infinite number spheres in cell, this obeys Percus-Yevick hard-sphere statistics. By construction, MC studied have same inclusion fraction. A constant-strain-tetrahedra displacement-based finite element code iterative solver is used calculate overall constants these realizations. It appears that scatter individual already obtained few dozen remarkably small averages varying numbers practically stationary.
