Conductivity and elastic stiffness of spherical particle composite with partially disordered microstructure

The spherical particle composite with the microstructure varying from perfectly ordered to completely disordered is considered. partially periodic packings of spheres are generated in framework reprehensive unit cell model aid Metropolis algorithm. orientation order invariants Q i introduced by Steinhardt et al. [ Phys. Rev. B 28 (1983) 784] molecular physics context taken as structural parameters providing a quantitative measure disorder. Variation these due gradual disordering cubic symmetry has been studied means computer simulation. effective conductivity and elastic moduli composites found multipole expansion method. Numerical study discovers close relationship between metrics macroscopic properties composite. micromechanics-prompted approximation this suggested tested on numerical data obtained
